(4.18 × 9) = 37.62
10^-4 × 10^-4 = 10^-8
Then since you need to move the decimal over to make it in scientific notation, you add 1 to the 10^-8 , then you get 10^-7. The problem in scientific notation is 3.726×10^-7.

Answer:
x = - 8
Step-by-step explanation:
Given
x + 2 = - x - 5
Multiply through by 8 to clear the fractions
2x + 16 = - 5x - 40 ( add 5x to both sides )
7x + 16 = - 40 ( subtract 16 from both sides )
7x = - 56 ( divide both sides by 7 )
x = - 8
Answer:
57
Step-by-step explanation:
h(-5) = (-5)^2 - 5(-5) + 7
h(-5) = 25 + 25 +7
h(-5) = 57
