Answer:
2x + 10
Step-by-step explanation:
the sum of two times a number means # times 2, and the number is unknown so you use x, and ten means +10 so that means that, THe sum of two times number and ten is
2x+10
256 in2 = s2
sqrt(256) = 16 → side length = 16
rectangle width = 16, length = 16+2 → 18
18 x 16 = 288 in2
Doubling the width would use less cardboard.
Justification:
Doubling the height will use 9in more cardboard
Doubling the width will only use 2 more inches of cardboard
