Answer:

x=7

Step-by-step explanation:

95+65=160

There is 360 degrees total in a quadrilateral

360-160=200

(15x-5)+100=200

15x+95=200

Subtract 95 from both sides

15x=105

x=7

Answer:

A) 2x³+11x²+8x-16

Step-by-step explanation:

When you multiply s(x) by t(x) you get something like this:

$s(x) \times t(x) = (2 {x}^{2} + 3x - 4) \times (x + 4) \\ = 2 {x}^{3} + 3 {x}^{2} - 4x + 8 {x}^{2} + 12x - 16 \\ = 2 {x}^{3} + 11 {x}^{2} + 8x - 16$
