When you combine like terms, you are able to solve the equation in less steps
3x=x+40
Subtract x from both sides
2x=40
Divide both sides by 2nto get x by itself
x=2
Plug 2 in for x
m∠4 = (3x)
m∠4 = 3(2)
Solve
m∠4 = 6
Answer:
(x-3)² + (y+2)² = 72
Step-by-step explanation:
center is halfway between (9,-4) and (-3,8).
average of x-coordinates = (9-3)/2 = 3
average of y-coordinates = (-4+8)/2 = -2
center: (3,-2)
length of diameter = √[(9-(-3))²+(-4-8)²] = √288 = 12√2
radius = 6√2
(x-3)² + (y+2)² = (6√2)² = 72
This is the simplified version 6x^2+9x+3.
Answer:
Write an equation in which the distributive property, commutative property, associative property, addition or subtraction property, and multiplication property can be used to find the solution. Then solve the equation. Justify each step.
