Step-by-step explanation:
First you remove the parenthesis, and you collect all the terms to give u and answer.
Answer:
9
Step-by-step explanation:
40 dollars due up front
10 dollars made per sale
5 dollars lost per creation
Realistically speaking she is only making a $5 profit per box she sells;
<em>$5 used up for material cost, $10 made from sales </em><em>-5+10= 5</em>
To pay the $40 dollar for the booth she would need to make 9 sales with her current profit
<em>40/5 = 9</em>
You have the polygon MNOPQR which can be expressed as two rectangles pasted one next to each other.
To see the two rectangles in the picture, you can draw a line parallel to segment MR througn point N.
From the original picture you can state the dimensions of both rectangles.
Call S, the point where the line that you drew intercepts the segment RQ.
Then one rectangle is MNSR and the other rectangle is OPQS.
The measures of the sides of the rectangle MNSR are:
- the length of MN = length of SR = base
- the length of MR = the length of NS.= height
So its area is base * height, which you can all A1.
The measured of the rectangle OPQS are:
- segment OP = segment SQ = segment QR - segment SR = base
- segment PQ = segment OS = height
So its area is base * height, which you can call A2.
Then the area of the polygon MNOPQRS is A1 + A2. One of them is 9 u^2 and the other is what the answer is asking for, and that you have calculated above.
With this procedure you can tell the value needed.
Answer:
11x +40
Step-by-step explanation:
Add 22 and 18 and the result will be as above.
So 1st make it equal to zero
x^2+4x-12
(x+6)(x-2)
so
x=-6 or 2 is the correct answer
