Answer:
x = 35 degrees
Step-by-step explanation:
the little box on the left side of the ttriangle means that is a 90 degrees angle.
So you add 55 + 90 = 145
Then subtract 180 - 145
which gives you 35
Answer:
-2
Step-by-step explanation:
1. Rewrite the equation:
2(3x - 3) = -18
2. Use the distributive property:
2(3x - 3) = -18 ---> 6x - 6 = -18
3. Add 6 to both sides:
6x - 6 = -18 ---> 6x = -12
4. Divide both sides by 6:
6x = -12 ---> x = -2
Now we know our answer is -2, let's make sure it's correct:
2(3x - 3) = -18
2(3(-2) - 3) = -18
2(-6 - 3) = -18
-12 - 6 = -18
-18 = -18
This tells us our answer is true!
Hope this helps :D

Answer:
A. 48r² - 10r + 3
Step-by-step explanation:
Solve (6r - 1) × (-8r - 3)
1. <u>Distribute 6r and -1</u> (into -8r - 3):
-48r² - 18r + 8r + 3
2. <u>Combine like terms</u> (-18r and 8r):
-48r² - 10r + 3
So, your answer is -48r² - 10r + 3
