Question

Solve for c. (c+9)2=64 A/1 and 17 B .−55−−√ and 55−−√ ​ C−73−−√ and 73−−√ ​ D −17 and −1

Answer 1

−17 and −1

Explanation:

Answer 2

c = -9 ±√8

Explanation:

You can solve for (c+9)²=64 by using inverse operations. Since the expression (c + 9) is under the operation of squaring, use a square root on both sides to undo it. Then continue using inverse operations to solve for C.

(c+9)²=64

√(c+9)² = √8

(c + 9) = ±√8

c = -9 ±√8
