Answer:

Step-by-step explanation:
We have the right triangle and the trapezoid.
The formula of an area of a right triangle:

a, b - legs
We have the length of the legs 12in and 13.42 in. Substitute:

The formula of an area of a trapezoid:

b₁, b₂ - bases
h - height
We have the length of the bases 18in and 11.75in and the length of the height 6.12in. Substitute:

The area of the figure:

Substitute:

Answer:
A
Step-by-step explanation:
14. 6/10
To solve this, multiply both numbers (numerator/dominator) by 2. It is the same amount, just written differently.
15. Lynn has more ribbon
This one is a little trickier. Find the fraction with the smallest dominator (bottom number) and multiply it by 2 to get 8. Then multiply the numerator (top number) by 2 as well. It ends up now being 6/8.
Answer:
5b+10
Step-by-step explanation:
This can be solved using the distributive property. You multiply 5 by b to get 5b, and then 5 by 2 to get 10. This then gives you 5b+10
