10) if 2(x + 3) = x + 10, then x equals
s

x = 4

Step-by-step explanation:

2(x+3) = x+10

2x+6 = x+10  Distribute 2 to x & 3

x+6 = 10  Simplify by subtracting x from both sides

x = 4  Last subtract 6 from both sides

(check answer by substituting x with 4, it should be correct if it's 14 = 14)

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
