Find all real square roots of -36

The answer is ±6.

Step-by-step explanation:

The positive and negative square roots of 36 are 6. and −6. Both 6, and −6 are square roots of 36 since they both give 36 when squared:...

6^2=6×6=36

(−6)2=(−6)×(−6)=36

All positive real numbers have a positive and negative real square root which are additive inverses of one another.

The principal square root is the positive one and is the one meant when we use the √... symbol. So:...

√36=6

If we want to refer to the negative square root, then just put a minus sign in front:...

−√36=−6

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16
