Hi there

(x² + 7x + 12)(x² + 3x + 5)
Distribute
(x²)(x²) + (x²)(3x) + (x²)(5) + (7x)(x²) + (7x)(3x) + (7x)(5) + (12)(x²) + (12)(3x) + (12)(5)
= x^4 + 3x^3 + 5x^2 + 7x^3 + 21x^2 + 35x + 12x^2 + 36x + 60
= x^4 + 10x^3 + 38x^2 + 71x + 60

Good luck !

Answer: It will take $\frac{7}{3}$ of an hour to complete the test.

Step-by-step explanation:

We need to convert the mixed number $1\ \frac{1}{3}$ to an improper fraction:

$1\ \frac{1}{3}=\frac{(1*3)+1}{3}= \frac{4}{3}$

Now, we need to make the following add the fractions in order to calculate how many hours will it take to complete the test. Then, we get:

$\frac{4}{3}+\frac{1}{3}+\frac{2}{3}=\frac{4+1+2}{3}=\frac{7}{3}$

Therefore, it will take $\frac{7}{3}$ of an hour to complete the test.
