Answer:
x² + 9x + 20
Step-by-step explanation:
Area of a rectangle can be found by multiplying the base with height (or length with width).
A(r) = l x h.
Multiply. Plug in:
x + 5 for l
x + 4 for h
A(r) = (x +5) * (x + 4)
Use the FOIL method to solve. Multiply the first terms of both parenthesis, the outside terms, the inside terms, and then the last terms. Combine like terms:
A(r) = (x + 5) * (x + 4)
x * x = x²
x * 4 = 4x
5 * x = 5x
4 * 5 = 20
x² + 4x + 5x + 20
x² + (4x + 5x) + 20
x² + 9x + 20
x² + 9x + 20 is your answer.

The velocity of the jogger will be 0.18 miles per minute.
<h3>What is velocity?</h3>
Velocity is defined as the ratio of the distance moved by the object in a particular time. The velocity is a vector quantity so it needs both the magnitude and the direction.
Given that:-
- It took the jogger 45 minutes to cover the 8 miles
The velocity will be calculated as:-
V = Distance ÷ Time
V = 8 ÷ 45
V = 0.18 miles per minute
Therefore the velocity of the jogger will be 0.18 miles per minute.

2. just do inverse transformation to get pre-image. simply do T(4,-3) to given vertices.
you'll get A(-1,1)B(7,1)C(7,-2)D(-1,-2)
5. dont know.
10.option 1 and 4
You would need a scientific calculator for this exercise.
On your calculator you simply enter the symbol e. (Please ensure your calculator has nothing on display before this)
After pressing the e button, you press the x raised to the power of y symbol and then input 3.32, as shown below;
70-30=40
40 divided by 8 = 5
x ≤ 5
