Answer:
It would be Choice C, 12.4 feet.
Step-by-step explanation:
By using Pythagoras Theorem a² + b² = c²
c²- b²= a²
13²-4²=
169 - 16 = √153
√153 = 12.3693168769
12.3693168769 ≅ 12.4

Answer:
x = -5
Explanation:
4(2x + 10) = 0
[ Simplify both sides of the equation ]
4(2x + 10) = 0
(4)(2x) + (4)(10) = 0 [Distribute]
8x + 40 = 0
[ Subtract 40 from both sides ]
8x + 40 − 40 = 0 − 40
8x = −40
[ Divide both sides by 8 ]
8x / 8 = −40 / 8
x = -5
