Answer:
x^3 -14x^2 -6
Step-by-step explanation:
Your expression is the difference of two polynomials. The parentheses can be removed by using the distributive property. The minus sign outside the second set of parentheses applies to each term inside parentheses.
-5x^2 +3 +x^3 -9x^2 -9
Now, you can group like terms. In "standard form", the degrees of the terms decrease from left to right.
x^3 +(-5x^2 -9x^2) +(3 -9)
And combine like terms.
x^3 -14x^2 -6 . . . . . simplified form of the given expression

Answer:
C 27 degrees
Step-by-step explanation:
The sum of the angles of a triangle add to 180. Let x be the third angle
62+ 91 +x = 180
Combine like terms
153+x = 180
Subtract 153 from each side
153+x-153 = 180-153
x =27
