Answer:
Step-by-step explanation:
(x - 8)/2 = -5
x - 8 = -10
x = -2
(y + 6)/2 = 10
y + 6 = 20
y = 14
(-2, 14)
Answer:
14
Step-by-step explanation:
(2 x 6) + (
- 8 ÷ 2^2) =
12 + (4 - 8 ÷ 4)

Answer:
6.3 feet
Step-by-step explanation:
use pythagorean theorem
a² + b² = c²
a² + 3² = 7²
a² + 9 = 49
Subtract 9 from both side
a² = 40
Take the square root of both sides
a = 6.324555320336759
Rounded
a = 6.3
