Answer:
No.
-3x-3=9, as 2 negatives multiply to a product that is positive.
9-1=8
8 does not equal 10.
Answer: ? = -22.5
Step-by-step explanation:
Using a negative number to replace the ? turns the minus into a plus sign.
-21 - (-22.5) = 1.5 is the same as -21 + 22.5 = 1.5
The area of the equilateral triangle is
90.084= 5
0.0009084= 4
The answer is 20x - 10.
Hope this helps!
