Answer:
C) (x-3)(x+3)
Note:
Just a tip there is an app called Desmos where you can put in equations like this and it will graph them for you.
3/2 because you divide both by 2
Answer:
x = 45
Step-by-step explanation:
x = (360 - 135 * 2) / 2
x = (360 - 270) / 2
x = 90 / 2
x = 45
Answer:
Step-by-step explanation:
The first thing you need to do is develop the equation. Less in this case means subtract.
On the left side you have
9 times a number which is 9*x
5 less than 9 times a number means 9x - 5
Now you shift to the right
x = 3
x + 19 What you get is
9x - 5 = x + 19 Subtract x from both sides of the equation
9x - x - 5 = 19 Combine both x terms on the left
8x - 5 = 19 Add 5 to both sides.
8x - 5 + 5 = 19 + 5 Combine terms
8x = 24 Divide by 8
x = 24/8
x = 3
