Use the distributive property to solve the equation -4(x+3)=8

algol [13]

Answer:

$x=-5$

Step-by-step explanation:

$-4(x+3)=8\\\\(-4)(x)+(-4)(3)=8\\\\-4x+(-12)=8\\\\-4x-12=8\\\\-4x-12+12=8+12\\\\-4x=20\\\\\frac{-4x}{-4}=\frac{20}{-4}\\\\x=-5$

The formula for perimeter of a rectangle is given by p = 2l + 2w, where p = perimeter, l = length, and w = width. solve the form

TiliK225 [7]

Perimeter formula
p = 2l + 2w

I reverse left-right side
2l + 2w = p

Move 2l to the right
2l + 2w = p
2w = p - 2l

Move 2 to the right
2w = p - 2l
w = (p - 2l)/2

Summary
p = 2l + 2w
2l + 2w = p
2w = p - 2l
w = (p-2l)/2

The range of a data set is the difference between the largest and the smallest value in the set.
Here the range is: r = 62 - 25 = 35
