Describe the error in solving for one of the variables in the linear system 4.2 + 3y = 8 and 2 - 2y = -13 Х
4x + 3y = 8
x - 2y= -13 Multiply by -4.
4x + 3y=8
-4x+8y= -13
11y= -5
-5
y=
11

step-by-step explanation:

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.

the answer is  

a.

4,624π mm2
