Answer:
K=2J+28
Step-by-step explanation:
Y intercept is 28
Slope is 2
<span>X, X+2, X+4 are the 3 consecutive positive even numbers
X(X+2)=8+38(X+4)
X^2+2X=8+38X+152
X^2+2X-38X-8-152=0
X^2-36X-160=0
(X-40)(X+4)=0
X=40 --> 1st integer
X+2 --> 40+2=42
X+4 --> 40+4 =44
ANSWER: 40, 42, 44</span>
Your answer is B because you do 0.5 times 7 you get 3.5 which is 3 1/2 ft
