Answer:
25%
Step-by-step explanation:
height grown in a year = 10 - 8 = 2

43x-3214 should be the answer
Answer:
(x+2)(x+4)
Step-by-step explanation:
Let us assume base of the window = b feet.
Height is 3 feet less than base, that is = (b-3).
Given area of the triangle = 20 feet square.
We know formula for area of a triangle:
Area =
× Base × Height
Plugging values in formula, we get
20 = 




Factoring quadratic, we get
=0
b+5=0
b=-5
b-8=0
b=8.
For base we can take only positive value.
<h3>Therefore, base of the triangle = 8 feet and height = 8 -3 = 5 feet.</h3>
Expressions are problems with no answer. I would use it to represent inequalities and/or a basic formula
