Q:
What is the combined perimeter of these two rectangles?A) 6x + 14 B) 12x + 24 C) 12x + 26 D) 24x + 52
Accepted Solution
A:
Answer:D) 24x + 52Step-by-step explanation:The perimeter of the shaded rectangleP = 2(l+w) = 2(4x+5 + 2x+7)Combine like terms =2( 6x+12)Distribute = 12x+24The perimeter of the unshaded rectangleP =2(l+w) = 2(3x+14 +3x) Combine like terms =2(6x+14)Distribute =12x+28Add the perimeters together12x+24+ 12x+28Combine like terms24x+52
