Answer:
<em><u>A rational equation is an equation containing at least one fraction whose numerator and denominator are polynomials, ... These fractions may be on one or both sides of the equation. A common way to solve these equations is to reduce the fractions to a common denominator and then solve the equality of the numerators.</u></em>

three shapes. three areas to find. three areas to add together to find the whole area. gotcha.
Step-by-step explanation:
- smaller rectangle
- larger rectangle
- right triangle
<h2>
smaller rectangle: </h2>
length is 7 cm and width is 4 cm, so the area is <u>28 square cm</u>
<h2>
</h2><h2>
larger rectangle:</h2>
width is 4 cm and length is 10 cm, so the area is <u>40 square cm</u>
Because the weird shape's bottom length was 13 cm. There are 3 cm and 7 cm on the top length(s) of the weird shape, next to each other. Looking at the dash lines, when adding 3 cm and 7 cm together, the larger rectangle's length is 10 cm.
<h2>right triangle: </h2>
base is 3 cm and height is 8 cm, so the area is (3x8)/2 = 24/2 = <u>12 square cm</u>
With knowledge from figuring out the larger rectangle's length being 10 cm and the weird shape's bottom length being 13 cm, we know the right triangle's base is 3 cm. (13 cm - 10 cm = 3 cm for the base of the right triangle).
Due to adding 4 cm and 4 cm of weird shape's width, which is also a right triangle's height.
<h2>weird shape's area from adding three shapes' areas: </h2>
28 + 40 + 12
= 80 square cm (ANSWER)

Hello!
The Roman numeral symbol for 5 is V, choice E.
I'll go through all the other choices.
Roman numeral I is 1.
Roman numeral L is 50.
Roman numeral M is 1000.
Roman numeral C is 100.
Finally, roman numeral D is 500.
Answer:
A new car costs $23,000. The value decreases by 15% each year.
An exponential model to represent the car's value after t years:
y = 23000 x (1 - 15/100)^year
= 23000 x (0.85)^year
Hope this helps!
:)
