Answer:
A) B is greater
B) when C = 21, A = 5 and B = 15
C) A must be 0, 5, or 12 for C to be greater than B
Step-by-step explanation:
A) when a = -3, c = -20 and b = 4(-3)-5 so B = -17
B) when c = 21, a = 5 and b = 4(5)-5 so B = 15
C) C is greater than B when a = 0, 5, and 12
when a = 0, b = 4(0)-5 or -5
when a = 5, b = 4(5)-5 or 15
when a = 12, b = 4(12)-5 or 43

Step-by-step explanation:
This is just stuff you have to memorize, I can’t really explain much further than product always means multiplication. The “product of” means k*m

The missing diagram is shown below. Remember that shapes are similar if you can turn one into the other by moving, rotating, flipping, or scaling. So this means you can make the object bigger or smaller. So in this case, we know that ΔABC is similar to ΔDEF. If so, we can establish the following proportion:

Our goal is to find x. So by Pythagorean theorem:

Conclusion:
<em>ΔABC ~ΔDEF</em>

Answer:
8 weeks
Step-by-step explanation:
Amount saved from mowing lawns = $433 - $145
