Write an expression to represent the perimeter of the triangle below in simplest form
Answers
Answer:
Perimeter of the given triangle = [tex]\frac{7x+38}{(x+8)(x+5)}[/tex] units
Step-by-step explanation:
Perimeter of a polygon = Sum of the measures of all sides of the polygon
From the picture attached,
Perimeter of the given isosceles triangle = Measures of two equal sides + remaining side
P = [tex]2(\frac{3}{x+8})+\frac{x}{x+5}[/tex]
= [tex]\frac{6}{(x+8)}+\frac{x}{(x+5)}[/tex]
= [tex]\frac{6(x+5)+(x+8)}{(x+8)(x+5)}[/tex]
= [tex]\frac{6x+30+x+8}{(x+8)(x+5)}[/tex]
= [tex]\frac{7x+38}{(x+8)(x+5)}[/tex] units
Therefore, perimeter of the given triangle is [tex]\frac{7x+38}{(x+8)(x+5)}[/tex] units

hope this helped :)
Answer:
-7 + 4r
Step-by-step explanation:
You need to combine like terms for this problem. All the basic numbers(without the r) are added together. -14 + 7 = -7. Then the numbers with the r's are added together. -9r + 13r = 4r. This comes out to -7 + 4r

Answers
Answer:
1. a
2. b
3. c
Step-by-step explanation:
1. a
For this first graph, we know that it matches a because of the domain. A tells us that the x≠-1. We know this because of the denominator.
(x+1)(x+1)=0 subtract both sides by 1]
x=-1
Therefore, a matches graph 1.
------------------------------------------------------------------------------------------------------
2. b
For graph 2, we can see that the graph is under the x-axis, meaning it is all negative. The only option that gives us a negative point is b. You can tell by the negative sign in front of the square root.
Therefore, b matches graph 2.
------------------------------------------------------------------------------------------------------
3. c
For graph 3, we see that everything is above the x-axis, meaning the graph is always positive. The option that fits this is c. In c, there are absolute values. Absolute values tell us that the answer is always going to be positive.
Therefore, c matches graph 3.

Answer:
x = 56
Step-by-step explanation:
Step 1: Write out equation
x + 20 + x + 48 = 180
Step 2: Combine like terms (x)
2x + 20 + 48 = 180
Step 3: Combine like terms (constants)
2x + 68 = 180
Step 4: Subtract 68 on both sides
2x = 112
Step 5: Divide both sides by 2
x = 56

Amy has $30 to spend she wants to buy 3 pounds of lemons at two dollars per pound a box of rice for four dollars and seven frozen dinners for three dollars each Will Amy have one dollar left over
Answers
Answer: Amy will not have one dollar left over , but she will have to add an extra dollar to buy all that stuff.
Step-by-step explanation:
First find the cost of the items she want to buy in total.
So she wants to buy 3 pound of lemons at two dollars per pound that will cost her $6.
Seven frozen dinners for three dollars each will cost her $21.
The box of rice will cost her $4.
Add the total cost together.
21 + 4 + 6 = 31
This means she will have to spend $31 in total and that is beyond her budget which is $30 dollars. This also means that Amy will not have one dollar left over but she will need to add one dollar.
Answer:
Amy won't have 1 dollar left, she will actually need 1 dollar because all of that would be 31 dollars.
Step-by-step explanation:
3 pounds of lemons= $6
1 box of rice= $4
7 frozen diners= $21
6+4=10
10+21=31
J is the midpoint of CT
T
If:
CJ = 4x - 9 and
JT = 9x – 34
Find CT.
Answers
Answer:
Step-by-step explanation:
4x - 9 = 9x - 34
-5x - 9 = -34
-5x = -25
x = 5
4(5) - 9 + 9(5) - 34
20 - 9 + 45 - 34
11 + 11 = 22
The value of CT such that J is the midpoint of CT will be 22.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
As per the given,
J is the midpoint of CT
CJ = JT
4x - 9 = 9x - 34
-9 + 34 = 9x - 4x
25 = 5x
x = 5
So CT = 2(CJ) = 2(4 x 5 - 9) = 22
Hence "The value of CT such that J is the midpoint of CT will be 22".

Answers
Answer:
13
Step-by-step explanation:
time=distance÷speed
650÷50=13
The time taken by the gorilla to hit the ground will be 13 seconds.
What is speed?Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.
Given that Thomas the giant gorilla climbed to the top of the building 650 feet tall. He broke loose a statue and threw it down with an initial velocity of 50 feet per second.
The time taken by the gorilla will be calculated by the formula of speed below,
Speed = Distance / Time
Time = Distance / Speed
Time = 650 / 50
Time = 13 seconds

Hello! I'm having a really hard time solving this by Elimination and could really use some help
Answers
Answer:
x= 3, y=0, z= 1
Step-by-step explanation:
Let's label the 3 given equations first.
2x +3y +4z= 10 -----(1)
3x +2y -4z= 5 -----(2)
x +4y +2z= 5 -----(3)
(1) +(2):
This is to eliminate the z term.
2x +3y +4z +3x +2y -4z= 10 +5
5x +5y= 15
Divide by 5 on both sides:
x +y= 3 -----(4)
(3) ×2:
2x +8y +4z= 10 -----(5)
(2) +(5):
This is to eliminate z term.
3x +2y -4z + 2x +8y +4z= 5 +10
5x +10y= 15
Divide by 5 throughout.
x +2y= 3 -----(6)
(6) -(4):
x +2y -(x +y)= 3 -3
x +2y -x -y= 0
y= 0
subst. y=0 into (4):
x +0= 3
x= 3
subst. x=3, y=0 into (3):
