Width : Length
2 : 5
Let x be the scale factor
Width : Length
2x : 5x
------------------------------------------------------------------------------------
Form equation and solve x
------------------------------------------------------------------------------------
Perimeter = 2(Length + Width)
70 = 2(5x + 2x)
70 = 2(7x)
70 = 14x
14x = 70
x = 5
------------------------------------------------------------------------------------
Find Length and Width
------------------------------------------------------------------------------------
Length = 5x
Length = 5(5)
Length = 25
Width = 2x
Width = 2(5)
Width = 10
------------------------------------------------------------------------------------
Answer: Length = 25 cm, Width = 10 cm

I can’t see it is to blurry
They gave you an eqution with variables and then they gave you numbers that all you have to do is put in
k(h-j)+h
5(5-4)+5
5(1)+5
5+5
10
Start by multiplying 3 times 3x to get 9x. Then multiply 3 times -6 to get -18
After that your equation is 18=9x-18
Then your going to add 18 to each side so your equation should be 36=9x
Then devide each side by 9 so the answer will be x=4
The phrase which describes the variable expression 8n is A. the product of 8 and n.
You get a product when you multiply, the quotient is when you divide, the difference is when you subtract, and sum when you add.
