Answer:
Length = 12 inches, height = 3 inches
Step-by-step explanation:
First, you have to set up a proportion. 2/7, x/42.
Then, you cross multiply and get the setup of 84=7x
Finally, you divide 84 by 7 and get 12.
12 is the length, and there is no other answer that has 12 in the height. You could just do the same proportion to get 3, though.
There is 2 figure here, a triangle and a parallelogram.
Area of parallelogram=base * height
A=9 * 5
A=45m²
Area of triangle=

(base * height)
A=

(9*8)
A=

72
A=36m²
36+45=81m²
The area of this figure is 81m²
Answer:
the answer to your question is (x+2) * (x-12)
These inequalities are not compatible: you are looking for a number that is less than 2, but more than 7. This is impossible, because if a number is less than 2, it can't be more than 7.
Conversely, if a number is more than 7, it can't be less than 2.
