Answer:
5x - 1
Find Factors:
6x²-5x-66x²-9x+4x-63x(2x-3)+2(2x-3)(2x-3)(3x+2)Factors: (2x-3)(3x+2)
Their sum:
(2x-3)+(3x+2)2x + 3x -3 + 25x - 1Factor the trinomial 6x²-5x-6, then find the sum of the factors .
Given : -An equation = 6x² - 5x - 6To Find : -Sum of their factors .Concept : -This question belongs to factorising the trinomial with the help of different methods such as middle term splitting .
Solution : -[tex] \longrightarrow \: 6x {}^{2} - 5x - 6[/tex]
Now , by splitting the middle term that is - 5 x :
[tex] \longrightarrow \: 6x {}^{2} - 9x + 4x - 6[/tex]
Now , taking 3x and -2 as common :
[tex] \longrightarrow \: 3x(2x - 3) + 2(2x - 3)[/tex]
So ,
[tex] \longrightarrow \: ( 3x + 2 ) ( 2x - 3 )[/tex]
Therefore , factors are ,
( 3x + 2 )( 2x - 3 )In the question we have ask to find the sum of their factors . So adding them ,
3x + 2 + 2x - 35x - 1Therefore , 5x - 1 is the sum of the factors .
#Keep LearningA custodian can clean 2 classrooms in 15 minutes. At this rate, how many classrooms can a custodian clean in 76 minutes?
Answer:
10 Classroom
Step-by-step explanation:
Since,
Custodian clean 2 classrooms in 15 minutes
Then ,
Let's see how many minutes does it takes for a custodian to clean for 1 classroom
To Find that we have to divide the given minutes by the given classroom.
15/2 = 7.5
Hence, in 7.5 minutes a custodian clean 1 classroom
Therefore:
Classroom to minutes:
1 = 7.5
2 = 15
3 = 22.5
4 = 30
5 = 37.5
6 = 45
7 = 52.5
8 = 60
9 = 67.5
10 = 75
11 = 82.5
Hence, we round to the nearest number:
which is 10 classroom in 75 minutes.
For this reason, the answer is about 10 classroom

Step-by-step explanation:
Someone please help, I've been stuck on this for so long!
Answer:
Step-by-step explanation:
Answer is C
Option A doesn't work since angle C doesn't equal to angle K even though they are alternate interior angles which means angle D won't equal to angle L so A-A theorem doesn't work
Option B: they aren't congruent (you can tell just by looking at them) congruent implies that they are identical in side length and angle
Option C: its option C since just by looking at the figure, we know that the side length arent the same, and non of the angles are congruent to each other (excpet angle J since its a vertical angle).
option D: not all triangles are similar

Answer:
(a) 136 ft
(b) $680
Step-by-step explanation:
You want to know the perimeter length and the cost of tiling around a pool with the L-shape shown.
(a) PerimeterThe sum of horizontal lengths at the bottom of the pool outline is the same as the length at the top.
The sum of vertical lengths at the left of the pool outline is the same as the length on the right.
The perimeter is the sum of horizontal and vertical lengths of the outline, so is ...
P = 2(40 ft + 28 ft) = 136 ft
The perimeter of the pool is 136 ft.
(b) Tile costThe cost of tile is found by multiplying the cost per length by the length around the pool.
tile cost = ($15/(3 ft))(136 ft) = $680
It will cost $680 to put tiles around the edge of the pool.

Find the area of a right triangle with a base of 9 feet and a hypotenuse length of 13 feet and a base of 9 feet.(Round to the nearest tenth.)
Answer:
Step-by-step explanation:
Remark
The plan is to find the third side. It and the 9 foot side form a right angle. The base is given as 9 feet. The third sid will be the altitutude. The formula is Area = 1/2 * Base * third side.
Formulas
c^2 = b^2 + a^2
Area = 1/2 b * a
Givens
c = 13 feet
a = ?
b = 9 feet.
Answer: 42.2 square feet.
Solution
c^2 = b^2 + a^2
13^2 = 9^2 + a^2
169 = 81 + a^2 Subtract 81 from both sides.
169 - 81 =81 - 81 + a^2 Combine
88 = a^2 Take the square root of both sides
√a^2=√88
a = 9.381
Area = 1/2 * 9 * 9.381
Area = 42.21
Rounded to the nearest 1/10 Area = 42.2

The area of the quadrilateral is equal to 15 square units.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the quadrilateral in a two-dimensional plane is called the area of the quadrilateral. A quadrilateral is a four-sided polygon with four edges and four corners in geometry.
Given that the quadrilateral has a height of 3 units, the base is 3 units and the upper sides are 7 units.
The area of the quadrilateral is calculated by the formula,
Area = (1/2) x h x (a + b)
Substitute the values in the formula and calculate the area,
Area = (1/2) x 3 x (7 + 3)
Area = (10 / 2) x 3
Area = 5 x 3
Area = 15 square units

The following m∠EGD, m∠DGC, m∠EGA lies on a straight line.
A straight line has total 180° interior angle.solve:
m∠EGD + m∠DGC + m∠EGA = 180°x + 90° + 30° = 180°x + 120° = 180°x = 180° - 120°x = 60°Students at Baldwin Elementary School cast 432 votes for student government president.

If w = 7 feet, x = 6 feet, y = 13 feet, and z = 8 feet, what is the area of the object?
Answer:
The Area is: 84ft
Step-by-step explanation:
multiply "Y" and "X" and you get 78ft.
"W" + "?"= "Y" If "W"=7, what is 13 ("Y") - 7? 13 -7=6. so "?"=6.
"Z"-"X"="?" "Z"=8 and "X"=6. so 8-6=2
2x6=12 *but remember that to find the area of a triangle it is half of a square of rectangle so you have to divide it in half. 12/2=6.
78+6=84.

There are 357 basketball fans who plan to go to a game. How many buses will be needed, given that each bus can hold 45 fans?
Answer:
8 buses
Step-by-step explanation:
So if we want to seperate out a group of objects to a set, we would used division. Our group of objects is basketball fans and our set is a bus.
Now, we divide the group of objects by the set, to find how many sets to fit all the objects.
357/45 = 7.93333
Since we have a mixed number with a fraction, we will always round up. Because we can't have part of a bus and if we round down, we will not have enough buses.
So we need 8 buses

Help With my math home work
Answer:
1/2 and -1/2
Step-by-step explanation:
The square root of a fraction is equal to the square root of the numerator divided by the square root of the denominator. In this case, it is √1 / √4. The square root of 1 is still 1, so 1 is the numerator. The square root of 4 is 2, so 2 is the denominator. The fraction is 1 / 2. However, if you square -1/2, you also get 1/4, just like when you square 1/2. Therefore, the second choice is the right option because it has the correct, and number of, answers.
