Answer:
choice 2) area = 319.2 in²
Step-by-step explanation:
triangular ends = 6.9 x 8 = 55.2
sides = 3 x 8 x 11 = 264
264 + 55.2 = 319.2 in²
<span>3 + (-1/4)² ÷ 1/2
= </span><span>3 + 1/16 * 2
= 3 + 1/8
= 3 1/8
answer
</span><span>D. 3 1/8</span>
Answer is: -17+6+(-3)=-14
Answer:
C
Step-by-step explanation:
The formula to find the slope of a line is:
(y2 - y1) / (x2 - x1)
We can substitute the points (-4, 7) and (5, -8) to find the slope:
(-8 - 7) / (5 - (-4))
(-15) / (5 + 4)
(-15) / 9
This can be simplified to
- 5 / 3
which is option C

Answer:
6x^2 +x -12
Step-by-step explanation:
Substitute for A and B and collect terms.
2B +3A
= 2(3x^2 -x +3) +3(x -6) . . . . substitute for A and B
= 6x^2 -2x +6 +3x -18 . . . . . eliminate parentheses
= 6x^2 +x -12 . . . . . . . . . . . . collect terms
