Answer:
B
Step-by-step explanation:
Area of rectangle = length * width
length * width = 160 square inches
(2x + 8) (2x +6) =160 {Use FOIL method}
(2x*2x) + (2x*6) + (8*2x) + (8*6) = 160
4x² + 12x + 16x + 48 = 160 {Add the like terms}
4x² + 28x + 48 -160 = 0
4x² + 28x - 112 = 0
Answer:
M (- 5, 2 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( , )
Here (x₁, y₁ ) = A (- 2, 8 ) and (x₂, y₂ ) = B (- 8, - 4 ) , then
midpoint = ( , ) = ( , ) = (- 5, 2 )
Answer:
work is shown and pictured
2(4*8) + 2(12*4) + 2(12*8)
= 352 cm^2
I took every face alone (6 in total) and multiplied Length by width. You have two from every face.
