V*7+3*v7+3 I’m not sure so I might be wrong

Answer:

49v^{2} +42v+9

Step-by-step explanation:

First, let me say, I'm not sure what exactly the equation is because it's worded weirdly, but I'm assuming it's (7v+3)^{2}.

(7v+3)(7v+3) [7v+3^{2} is the same as (7v+3)(7v+3).]

49v^{2}  +42v+9 [When you multiply them, this is the product.]

This is as far as you can simplify without knowing the value of v as far as I know.

If 10 pencils and 7 erasers cost $4.23 and 3 pencils and 1 eraser cost $0.95, what is the cost of 2 erasers?
QveST [7]

Answer: $0.58

<u>Step-by-step explanation:</u>

Let x represent pencil and y represent eraser

10x + 7y = 4.23   →   1(10x + 7y = 4.23)   →   10x + 7y =  4.23

3x  + y  = 0.95   →  -3(3x  + y  = 0.95)   →   <u>-21x - 7y</u> =<u> -6.65 </u>

                                                                    -11x         = -2.42

                                                                  <u>÷-11          </u>   <u>÷-11       </u>

                                                                         x        = 0.22  

      3x + y = 0.95

3(0.22) + y = 0.95

   0.66 + y = 0.95

               y = 0.29

2y = 2(0.29)  = 0.58
