Answer:
357
Step-by-step explanation:
A) We replace x = - 5 and u = 3 into -3x^3 -2y^2
and we have -3x^3 -2y^2= -3*(-5)^3 -2*3^2= -3*(-125)- 2*9
or -3x^3 -2y^2 = 375-18= 357
The answer is 357.
B) Replace h = -2 into h^2-3h+2
we have h^2-3h+2 = (-2)^2 -3*(-2) +2 = 4 +6 + 2= 12
The answer is 12

It can be noted that the percentage error made by Allison will be 1.6%
<h3>How to solve the percentage</h3>
From the information given, Allison measured a line to be 19.4 inches long and the actual length of the line is 19.1.
Therefore, the percentage error will be:
= (19.4 - 19.1)/19.1 × 100
= 0.3/19.1 × 100
= 1.6%
In conclusion, the correct option is 1.6%.
