b = 21
In this problem, we aren't finding the hypotenuse, but a side...
Using Pythagoras' theorem
side² = hyp² – side²
b² = 29² – 20²
b² = 841 – 400
b² = 441
b² = √441
b = 21
Therefore b = 21
Answer:
It should be A 3 1/4
Step-by-step explanation:
I’m pretty sure the answer would be -29 2/3
Answer:
16
Step-by-step explanation:
b=16
Following the pattern, we can assume that each term adds by 1. So 15+1 = 16.
Group
c(x)=(x²-16x)+84
take 1/2 of -16 and square it
-16/2=-8, (-8)²=64
ad negative and positive inside
c(x)=(x²-16x+64-64)+84
factor
c(x)=((x-8)²-64)+84
distribute or get rid of paenthsees
c(x)=(x-8)²-64+84
add
c(x)=(x-8)²+20
