-5(5-3v)=-115<br> Helpp me please
prisoha [69]

we start by opening the brackets so it will be -25 plus 15 v is equals to 115. negative times a negative is a positive so -5 times -3 we we have gotten positive 15v there I hope you understood so our new equation is -25 + 15v is equals to 115 collect the like terms 15v is equals to 115 + 25 15 v is equals to 140 divide both sides by 15 so v is equals to 9 and 1/3

Suppose the side lengths are multiplied by 2. Describe the change in the perimeter
max2010maxim [7]

Answer:

The perimeter would also be multiplied by 2.

Step-by-step explanation:

The perimeter would also be multiplied by 2. Suppose the sides of a triangle are 5, 10 and 13. The perimeter would be the sum of the side lengths or 5 + 10 + 13 = 28 ft.

Multiply each side length so 5*2 = 10, 10*2 = 20 and 13*2 = 26. Find the perimeter by finding their sum, 10 + 20 + 26 = 56.

Divide the new perimeter by the old perimeter to find a scale factor.

56/28 = 2.

The new perimeter is exactly 2 times bigger since 2*28 = 56.
