Answer:
multiply 4x12 and leave it inside the parenthesis, then multiply the 3 with 48
Answer:
A.
Step-by-step explanation:
1) to rewrite the given equation:
f(x)=2(x²+4x)-3; ⇔ f(x)=2(x²+4x+4)-3-8; ⇔ f(x)=2(x²+4x+4)-11; ⇔ f(x)=2(x+2)²-11;
2) the roots are:

3) finally, the correct answer is A.
Answer:
D
Step-by-step explanation:
The y-intercept must be at -7, so that eliminates C.
Because of the direction of the line, the slope needs to be negative. This eliminates B.
The slope of the line is -7/6, so D is the correct answer.

Answer:
2 numbers that multiply to make -21 = 3 x (-7)
2 numbers that add up to -4 = 3 - 7
Step-by-step explanation:
2 numbers that multiply to make -21 = 3 x (-7) = -21
2 numbers that add up to -4 = 3 - 7 = -4
