The second of 2 numbers is 5 more than twice the first. Their sum is 29. Find the numbers. (With steps)

hodyreva [135]

So the equation is x + 2x + 5= 29
Here are the steps            -5    -5
                               -----------------------
                                        3x   = 24
      Divide both sides by 3 so you get
                                          x = 8
Then look back at the question, the second number has to be twice that number plus 5
                 So the 1st number is 8 The second # is 2(8)+5= 21

Clara found the product of 3 – 6y2 and y2 + 2. Her work is shown below. (3 – 6y2)(y2 + 2) = 3(y2) + (–6y2)(2) = 3y2 – 12y2 = –9y

Answer:

No, She did not use the distributive property correctly.

Step-by-step explanation:

While multiplying $(3-6y^2)(y^2+2)$ , he did not use distributive property correctly. She only multiplied 3 with $y^2$ and not with 2. Also she multiplied $-6y^2$ only with 2 and not with $y^2$ .
