522
Step-by-step explanation:
754/13=58
58 times 9 is 522
-61
(-22)-39=-61
the answer is in the picture
9514 1404 393
x^3 -x^2 -17x +12
Use the distributive property and collect terms.
(x +4)(x^2 -5x +3) = x(x^2 -5x +3) +4(x^2 -5x +3)
= x^3 -5x^2 +3x +4x^2 -20x +12
= x^3 -x^2 -17x +12
105
First find the third angle inside the triangle:
180 - 30 - 75 = 75
Then find x:
180 - 75 = 105
