Hey there! :D
Remember that the question said estimate.
So
47% rounds to 50%
.5 and 1/2 are equal to 50%
89 rounds to 90.
You could say that:
1/2*90
0.5*90
90/2
These will all work and will give you the same answer.
I hope this helps!

Multiply .30 and 50 ... which is 15
You can use prime factorization to figure this out.

4 x 14 = 56
4 + (14) = 18
Final answer: </span>4 and 14
1575 cubic inches
This is the answer to your question.
2x^3-42x-40=0
2x^3-42x=40
2x(x^2-21)=40
a. 2x=40=>x=20
b. x^2=21+40=>x^2=61=>x=+-(radical(61)
