Answer:
-8x^2+26x-21
Step-by-step explanation:
(3-2x)(4x-7)
12x-8x^2-21+14x
-8x^2+12x+14x-21
-8x^2+26x-21
Answer:
472 in²
Step-by-step explanation:
This net is made up of 3 identical rectangles and 2 identical triangles.
Area of a rectangle = width x length
Area of a triangle = 1/2 x base x height
<u>Rectangle</u>
- width = 8 in
- length = 19 in
<u>Triangle</u>
<u>Surface Area</u>
SA = 3(8 x 19) + 2(0.5 x 8 x 2)
⇒ SA = 456 + 16
⇒ SA = 472 in²
The top one on the left is equivalent to the second one down on the right; the second one down on the left is equivalent to the bottom one on the right; the third one down on the left is equivalent to the second one down on the right, and the last one on the left is the only one remaining on the right.
