We know that:

Then:

Therefore:

Simplifying the above result we get:

Answer:
F = 1.8C + 32
F = 1.8(100) + 32
F = 180 + 32
F = 212 degrees
It’s definitely A
Ex: f(x)=8x+2
f(x)=8(-4)+2
f(x)=-32+2
f(x)=-30
Assuming the frame is rectangular, the perimeter is 2*width + 2*length. so 5*2 + 2*length = 24. subtract ten from both sides to get the 14 = 2*length. the length = 7.
