Answer:
15x+45-2x=15x-2x-10
13x+45=13x+10
13x-13x=10-45
if you simplify further
you will not get an answer there is a mistake in the question
Answer:
Here, length is 8 in. Width is 4in. and height is (3+3+3)=9 in. Then use the formula.
A= 2wl+2hl+2hw
= 2×4×8 + 2×9×8+2×9×4
=280 inch²

Answer:
Step-by-step explanation:
A is the correct answer
Answer:
8x+24
dimensions of the photograph
length - 7 inch
width - 5 inch
dimensions of the photo frame is 2x larger than both width and length
length - 7 + 2x
width - 5 + 2x
the perimeter is sum of all 4 sides
Perimeter = 2(7 + 2x) + 2(5 + 2x)
= 14 + 4x + 10 +4x
= 24 + 8x
correct answer is 8x+24
