Answer:4((x+3)(x-1))
Step-by-step explanation:
Factorize the common terms
4(x^2+2x-3)
Factorize
X^2+2x-3=(x+3)(x-1)
(X+3)(x-1)
4((x+3)(x-1))
Answer:
12
Step-by-step explanation:
13 + 6 + 2x -18 = 4x - 29
19 + 2x -18 = 4x -29
2x + 1 = 4x - 29
30 = 2x
15 = x
CD = 2(15) -18
CD = 30 -18
CD = 12

Answer:
11 units
Step-by-step explanation:
The height of a trapezoid is the distance between the parallel bases.
__
Here, one base lies on the horizontal line y=5, and the other lies on the horizontal line y = -6. The distance between them is ...
5 -(-6) = 5 +6 = 11
You can also find this distance by counting the grid squares between the two parallel lines.
The height of the trapezoid is 11 units.
_____
<em>Additional comment</em>
The base lengths are ...
AB = 2 -(-5) = 7
CD = 8 -(-7) = 15
The area is 1/2(b1 +b2)h = (1/2)(7 +15)(11) = 121 square units.
