Answer:
25
Step-by-step explanation:
I got 25, because I worked it out and if you plug in 25 to the equation when adding all of the angles and making them equal to 180 degrees, you end up with the remaining degrees to be 25, leaving angle C at 25 degrees. I hope this helps.
Answer:
x = -27
Step-by-step explanation:
4(x+5) - 13x = 263
Multiply
4x + 20 - 13x = 263
Subtract 20 from both sides
4x - 13x = 243
-9x = 243
Divide by 9 on both sides
x = -27
Hope this helps :)
12 x 2 = 24
When you multiply two negative numbers, the answer will be a positive
When you multiply one negative and one positive, the answer will be negative.
Using that rule:
(-12)(-2) = 24
24 is your answer

3.√(27x^9) = (27x^9)^(1/3) = 3x^3
