A: Foil
(b+2)(b+2)=b²+2b+2b+4=b²+4b+4
B: Again, Foil
(x+3)(x-3)=x²+3x-3x-9=x²-9
Answer:
D
Step-by-step explanation:
6x^2 + 10x^2 = 16x^2
2x-x = x
-8 + 14 = 6
16x^2 + x + 6

Answer: y=3x-5
Step-by-step explanation: Find the slope of the original line. slope is m=3. Then use the point slope formula to find the line parallel to y=3x+4. Parallel lines have the same slope. so you substitute the given point (x1,y1)(1,-2) and slope m=3 into the point slope formula.
y-(-2)=3(x-1)
y+2=3x-3
y=3x-5
