Answer:
B. 140 in^2
Step-by-step explanation:
A = 1/2(b1 +b2)(h)
=1/2(15 + 4 + 15 + 6)(7)
=1/2(40)(7)
= 140 in^2
Answer:
67 and -1
Step-by-step explanation:
You always multiply first so its 7+64-4 and that becomes 67
You have to distribute first so the problem would be 5-21+15 which is -1
Answer:
61 - 10x
2k
42 / 6 = 7
38 + 2m
3y - 6
Step-by-step explanation:
A. Sixty-one diminished by ten x
= 61 - 10x
B. The product of twice a number k
= 2 * k
= 2k
C. The quotient of forty-two and six is seven
42 / 6 = 7
D. Twice the total of nineteen and a number m.
= 2(19 + m)
= 38 + 2m
E. Six less than 3 times y
3y - 6
F(x) = 2x² + 7x - 5
g(x) = -8x² - 3x + 5
g(x) + f(x) = -8x² - 3x + 5 + 2x² + 7x - 5 = - 6x² + 4x
Answer: -6x² + 4x
