There are many factors, it is all a matter of preference, normally, you want to try to solve for the easiest one to get to
example
if y ou had
(x-3)^2+y=9
you would solve for y becuase it is less tricky
it is all a matter of preference
Answer:
12
Step-by-step explanation:
15 feet total amount combined by pole and birdhouse
4 foot tall person makes 5 feet long shadow
5x3=15
4x3=12 so the birdhouse and pole are 12 feet
Answer:
a. 10x + 4; the answer is a polynomial
Step-by-step explanation:
The perimeter of a rectangle is the sum of the lengths of the 4 sides.
The closure property is that if you add polynomials, the sum is a polynomial.
A rectangle has two congruent lengths and two congruent widths.
Since the length of the rectangle is 3x + 5, there is another length of 3x + 5. The width is 2x - 3, so there is a second width of also 2x - 3.
Let's add the 4 sides together:
3x + 5 + 3x + 5 + 2x - 3 + 2x - 3 =
= 3x + 3x + 2x + 2x + 5 + 5 - 3 - 3
= 10x + 4
The perimeter is 10x + 4. Each side length is a polynomial, and the sum of the all the side length is also a polynomial. This shows there is closure for the addition of polynomials.
Answer: a. 10x + 4; the answer is a polynomial
