Answer:
I will be using differentiation method
Step-by-step explanation:
x^2+5x =-8
2×x ×x^2-1 +5x = -8
2x +5x = -8
7x = -8
divide both sides by the co-efficient of x
7x÷7=-8÷7
x =-1.5
y = -3x + 8
-24r - 7
-6(4r + 2) + 5
-24r - 12 + 5
Best of Luck!
I'm pretty sure it's 28 but sorry if I'm wrong it might be 44
