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
He is wrong, it is 38000
38496, the 8 is the thousand spot
round the number after it up or down
4 rounds down and 9&6 go down with it
38,000
The scale factor is 5. 2 corresponds to 10 and 3 corresponds to 15. 1 must correspond to x, which is 5 times 1. The answer is x = 5.
