Answer:
Step-by-step explanation:
x²-10x = 12
Coefficient of the x term: -10
Divide in half: -5
Square it: (-5)² = 5²
Add 5² to both sides:
x²-10x+5² = 12+5²
(x-5)² = 37
Answer:
A =153.86 cm^2
Step-by-step explanation:
The diameter is 14 so the radius is d/2 = 14/2 = 7
A = pi r^2
A = (3.14) (7)^2
A =153.86 cm^2
Answer:
The next 3 steps are:
#1:
-- Using the square root method, we're going to find the square root of both sides.
#2:
-- When finding the square root of 10 it has to be + and minus.
#3:
-- Subtract 2 on both sides
#4 (solution):
