Quesition ?: 1. Look at the expression given before answering the questions that follow: \[ 7 x^{3}+3 x^{3} y^{2}-7 x^{1} y+8 x-12 \] a. What are the variables in this expression? b. Are there any "like" terms in this expression? yes

In the \( x y \)-plane, a parabola has vertex \( (9,-14) \) and intersects the \( x \)-axis at two points. If the equation of the parabola is written in the form \( y=a x^{2}+b x+c \) where \( a, b \), and \( c \) are constants, which of the following could be the value of \( a+b+c \) ? (A) -23 (B) -19 (D) -12

1) \( \frac{10 x+8}{3 a-b}-\frac{9 x+5}{3 a-b}= \)

8. \( \frac{\sqrt{27 a^{3} b^{6}}}{\sqrt{3 a b^{6}}-5 a b^{2}}= \)

Subtract the polynomials: \( (5x^{3} + 2x^{2} - 7) - (3x^{3} - x^{2} + 4) \)

5.7 Determine the equation of \( h \) if \( h(x)=g(x+1)-2 \)
