Answer:
The scale factor is 3/2.
Step-by-step explanation:
Let's use the side PQ.
The original length was 8 units.
And the new length is 12 units.
Let the scale factor be k. Therefore:
By dividing both sides by 8, we can see that our scale factor from ΔPQR to ΔP'Q'R' is:
Y=(-30-2x)/9 the slop is -2/9 because perpendicular to the given line so the new slop is 9/2
y=9/2x+b
0=9/2*-8+b
0=-36+b
b=36
y=9/2x+36 is the answer

Answer:
a) F(d)=350+0.06d
b)$390.2
Step-by-step explanation:
350+0.06(670)=390.2
2 (4 x 5) + 2(5 x 6 ) + 2 (6 x 4) = 148 m^2
answer = 148 m^2
