Solve 4x - 9 = 15

2 answers:

7 0

It’s b because negative 9 turns into positive 9 to cancel out the number to isolate variable. Then you also add positive 9 to 15 and that makes 24. But don’t forget about 4x which divide into 4x/4 and 24/4 to again isolate the variable. Then 24/4 = 6

4x - 9 = 15

Add 9 on both sides (-9 + 9 cancels out and 15 + 9 = 24)

4x = 24

Divide by 4 on both sides (4 / 4 cancels out and 24 / 4 = 6)

x = 6

The answer is B

What is the measure of AC?

Jlenok [28]

Answer:

5 blocks

Step-by-step explanation:

Since the triangle is right use Pythagoras' identity to solve for AC

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

AC² = AB² + BC² ← substitute values

AC² = 3² + 4² = 9 + 16 = 25 ( take the square root of both sides )

AC = $\sqrt{25}$ = 5
