<em><u>Answer:</u></em>

<u><em>Step-by-step explanation:</em></u>

When we want to find the value of an expression and we know the unknown values of the variables, we just have to plug them in:

b^2 + 4, and we know b = -3

= (-3)^2 + 4

= 9 + 4

= 13

Jamie can read at a speed of 65 pages per hour. If she reads a novel that has 400 pages, how long will it
horsena [70]
To find the answer set up an equation:
400 \: pages \times  \frac{1 \: hour}{65 \: pages}  =
Using this set up we can cross our units of pages since they are on opposite side of the proportion, leaving us with the desired units of hours.

Then divide 400 by 65 which will give us our answer: 6.15 or about 6 hours for Jamie to finish her reading.
