Answer:
358
Step-by-step explanation:
f(x) = 3x² - 5
f(-11) = 3(-11)² - 5
f(-11) = 3(121) - 5
f(-11) = 363 - 5
f(-11) = 358
what's the perimeter
Answer:
20
Step-by-step explanation:
You have to add the two equal sides (6)+(6) + 8
Answer:
20
Step-by-step explanation:
since there's a dash in the side with length of 6 that means that the sides are the same length. so 6+6=12+8=20.
hope this helped :)

how to solve
[tex] \sqrt{4} x {}^{2} = x + 2[/tex]
Answer:
➩ [tex]x=2,-\frac{2}{3}[/tex]
Step-by-step explanation:
[tex]\sqrt{4x^2}=x+2[/tex]
➨ We can also solve by completing both squares, however. Since we can pull out the square root.
[tex]\sqrt{4x^2}=|2x|[/tex] ➩ Define of Absolute Value/Square Root
➩ [tex]\sqrt{x^2}=|x|[/tex]
Thus, our new equation is ➩ [tex]|2x|=x+2[/tex]
To solve an absolute-value equation, let there be two conditions.
➨ Where x ≥ 0
[tex]2x=x+2\\[/tex]
Move x to another side
[tex]2x-x=2\\x=2[/tex]
➨ Where x < 0
[tex]-2x=x+2\\-2x-x=2\\-3x=2\\x=\frac{2}{-3}\\x=-\frac{2}{3}[/tex]

CELL PHONES A Cell phone company is going to build three new towers in a nearby city. The city council has
released s map that shows where the towers will be built. On the map, the distance between towers A and B is 2
centimeters, the distance between towers B and C 3 centimeters, and the distance between towers A and C is 4
centimeters. A technician needs to visit the stes of the three towers, and he has outlined his travel route between
them on a map. The polygon formed by his travel route on the map will be similar to the polygon formed by the
technicians he drives to the three towers. If the actual distance between tower Band tower C is 600 meters, how
for was the technican have to travel to visit all three cell phone towers?
Answer:
Distance between A ----> B : 2 cm
B ---> C: 3 cm : 600 meters
A----> C: 4 cm
3:600 meters scaled
So its 200 meters per every 1 cm!
From A to B : 400 meters
From B to C : 600 meters
Frok C to A: 800 meters
Therefore we sum 400+600+800= 1800 meters
Which is an equation of the line that passes through (0, -3) and is perpendicular to the graph of the line y=2x-3?
Answer:
D
Step-by-step explanation:
perpendicular to 2 =x is -1/2x, and (0,-3) just happens to be on the y intercept so its -1/2x - 3

Answer:
C. [tex]\frac{12}{7}[/tex]
Step-by-step explanation:
To find the slope when you know two points, use this formula:
M = y₂ - y₁ ÷ x₂ - x₁
M = (4 - (-8)) ÷ (0 - (-7))
M = 12 ÷ 7
M = [tex]\frac{12}{7}[/tex]

Here is a riddle: “I am thinking of two numbers that add up to 5.678. The difference between them is 9.876. What are the two numbers?”
The riddle can be represented with two equations. Write the equations
Answer:
X + Y = 5.678
X - Y = 9.876
The two numbers: X = 7.777 Y = -2.099
Step-by-step explanation: solve by elimination
X + Y = 5.678
X - Y = 9.876 . Add the two equations so the y cancels. Solve for x
2x = 15.554 . Divide both sides by 2
X = 7.777 Substitute in the original equations to find Y
7.777 + y = 5.678 . Subtract 7.777 from both sides
Y = - 2.099
check in the second equation:
7.777 -(-2.099) = 9.876
7.777 + 2.099 = 9.876 True
The two numbers is X = 7.777 and Y = -2.099.
And, the two equation is X + Y = 5.678 and X - Y = 9.876.
Given that,
I am thinking of two numbers that add up to 5.678. The difference between them is 9.876.Here we assume the one number be X and the other number be Y.
Based on the above information, the calculation is as follows:
X + Y = 5.678
X - Y = 9.876
2x = 15.554
X = 7.777
Now
7.777 + Y = 5.678
Y = - 2.099
Therefore, the above should be the answers.

Dora has 20 donuts. she divides those 20 donuts into halves. then she divides those halves into fifths. then she divides those fifths into thirds. how many pieces does she have now?
Answer:
270
Step-by-step explanation:
if u cut a donut in too halfs there are more donuts so 20* 2 is 40 then multiply 40 by 5 since she cuts it into fifths an u get 90 then multiply 90 by 3 since its thirds an you get 270
Answer:
600

1) Jayden runs 1/4 of a mile in 1/4 of an hour. How far will it take him to run 1hr.
2) Dylan walked 1/3 miles in 20 minutes How far will he goes in miles distance in 120 minutes?
Answer:
Question 1 : If you mean how many miles will he run in 1 hour then it is 1 Mile | Question 2 : 2 Miles
Step-by-step explanation:
Question 1 :
1/4 x 4 (because of the hour being split into fourths) = 1 Mile
Question 2 :
120 / 20 = 6, 6 x 1/3 = 6/3, simplified = 2
