No, because if x was 2:
5(2) + 3(2)= 10+6
=16
5(3) + 2y= 15 + 17y, it would already be to high of a number

4x2 + 8x - 7 - (3x2 - X+9)

Andreas93 [3]

Answer:

Step-by-step explanation:

$4 {x}^{2} + 8x - 7 - (3 {x}^{2} - x + 9)$

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression:

$4 {x}^{2} + 8x - 7 - 3 {x}^{2} + x - 9$

Collect like terms

$4 {x}^{2} - 3 {x}^{2} + 8x + x - 7 - 9$

${x}^{2} + 9x - 7 - 9$

Calculate

${x}^{2} + 9x - 16$

Hope this helps...

Good luck on your assignment...
