19.

P = 2(x - 3 + 7x + 1)
= 2(8x - 2)
= 16x - 4

20.

P = 3y + 5 + y - 4 + 6y
= 10y + 1

Plz I need some help with 11-12 . My teacher didn’t even explain it correctly so now I’m confused.

Answer:

Step 1: Transpose everything to one side

12. x²+16x+15-10x+4=0

Step 2: Add the like terms

x² + (16x - 10x) + 15 + 4=0

x² + 6x + 19=0

Step 3: Use the quadratic formula to get the value(s) of x.

a=1 b=6 c=19

$x = \frac{ - b + - \sqrt{b {}^{2} - 4ac } {}^{} }{2a}$

therefore, x=... or x
