Remember you can do anything to an equation as long as you do it to both sides (except divide by 0)
add like terms
3x-x=3x-1x=2x
so
3x-x+2=12
2x+2=12
subtract 2 from both sides
2x=10
divide both sides by 2
x=5
6 × 6 × 6
= 216
the answer is c.216

Answer:
The vertex is (0, 0).
Step-by-step explanation:
Check out the parent function: y = x^2. The graph is a parabola whose vertex is (0, 0) and which opens upward.
Then y = -x^2 is the same but opens downward. The vertex is (0, 0).
Answer:
b) 43.3
Step-by-step explanation:
you use the trig ratio tangent because you are looking for the hypotenuse
so the equation should be <u>tan60</u> = <u>x </u>
1 25
and then you solve for that by cross multiplying and you get 43.3
