Answer:
Solutions of the given equations is (-3,2).
Step-by-step explanation:
Here the equations given are y = -x²-6x-7------(1)
and y = 2---------(2)
Now we substitute the value of y from equation (2) into (1)
2 = -x²-6x-7
x²+6x+7 = -2
x²+6x+7+2 = 2-2
x²+6x+9 = 0
x²+3x+3x+9 = 0
x(x+3)+3(x+3) = 0
(x+3)(x+3) = 0
therefore value of x is x = -3
Therefore the solution is (-3,2).
Answer: c. P=43
d. P=3x^2+5x+8
Step-by-step explanation:
c. P=12x+19 ==> See how I got this formula in my previous answer to parts a and b
P=12(2)+19
P=24+19
P=43
d. P=a+b+c+d
P=x^2 +4x+8+2x^2 +x
P=x^2 +2x^2 +4x+x+8
P=3x^2+5x+8
