<u>ANSWER</u>

<u>EXPLANATION</u>
When a quadratic equation is in the vertex form,

the equation of axis of symmetry is simply

The given quadratic equation is

We can rewrite this as

We now compare to

We have

Therefore equation of axis of symmetry is:

Answer:
you have to use the Pythagorean theorem. a^2 + b^2= c^2
72^2 + b^2 = 75^2
5184 + b^2 = 5625 (subtract 5184 from both sides)
b^2= 441 (find the square root of each side)
b= 21
Answer:
<h2>x = 1</h2><h2 />
Step-by-step explanation:
3x + 1 = 7 - 3x
3x + 3x = 7 - 1
6x = 6
x = 6/6
x = 1
