Answer:
|8| = 8
|-8| = 8
Step-by-step explanation: its simple
Answer:
6
Step-by-step explanation:
11 1/2 = 11.5
2 1/4 = 2.25
11.5 ÷ 2.25= 5.11
she needs 6 containers because you round up 5.11 to 6.
if your doing the work in fractions rather decimals let me know and I can explain it that way too
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
