Answer:
The formula to find the perimeter of a rectangle is 2*length + 2*width
2(2x+1)+2(x^2+2x-1)
First we want to distribute the 2 through both the length and the width
(4x+2) + (2x^2+4x-2)
After we distributed the 2 through like we did up above, we now want to add them together to find the perimeter.
We want to combine all like terms
2x^2, doesn't combine with anything so we leave it the same
4x+4x=8x, add the coefficients and leave the variable
2-2=0, we just leave that out, don't do anything with it
What we have left is:
2x^2+8x,
Which would be C), if the answer is 2x to the second power+8x,
Hope this helps ;)
Answer:
34 pairs of shoes.
Step-by-step explanation:
Given:
On Monday,a shoe store sold 25 pairs of shoes.
On Tuesday they sold 17 pairs of shoes.
On Wednesday 8 pairs of shoes were returned to the store.
Question asked:
How many pairs of shoes did the shoes store sell without being returned?
Solution:
Total sell of pairs of shoes by the shoes store = 25 pairs + 17 pairs
= 42 pairs of shoes.
Pairs of shoes returned = 8 pairs
<u>Now, actual sell of pair of shoes = Total sell of pairs of shoes - Pairs of shoes returned </u>
Actual sell of pair of shoes = 42 - 8 = 34 Pairs of shoes
Thus, 34 pairs of shoes, the shoes store sold without being returned.
Area of a triangle=1/2(base x height)
Area=72, Base=8, Height=2x-3
Plug it in.
72=1/2(8 x (2x-3))
72=1/2(16x-24)
72=8x-12
84=8x
x=10.5
The inequality is: 5>x≥0
Step-by-step explanation:
We have to write the inequality one by one
The inequality symbols are used to write inequalities.
So,
5 is greater than x will be written as:
5>x
And
0 is less than or equals to x:
0≤x or x≥0
We have to combine the both inequalities so that the variable is not repeated. The inequality symbols have to be written carefully while writing the compound inequalities.
5>x≥0
