Answer:
K=14
Step-by-step explanation:
A=1/2*b*h
80=1/2*8*(6+k) multiply by 2 on both sides
160=8*(6+k) distribute by 8
160=48+8k subtract 48 from both sides
112=8k divide by 8
14=K
X^2 - 2x - 8 = <span>(x + 2)(x - 4)
</span>reciprocal of x^2 - 2x - 8 = 1 / [(x + 2)(x - 4)]
<span>
answer is </span><span>C. 1 / [ (x + 2)(x - 4) ]</span>
Answer:
Step-by-step explanation:
4^3 × 4^n = 4^12
Using indices multiplication rule
4^(3+n) = 4^12
4 cancelled out 4
Therefore: 3 + n = 12
n = 12 - 3
n = 9
