We can combine x + x and get 2x. So we have:

8x - 2y + 2x

8x -2y + x+x simply combine like terms 8x+ x + x= 10x therefore 10x-2y is equivalent

1. Describe how factoring a quadratic expression ax2 + bx + c, where a ≠ 1, is different from factoring x2 + bx + c.
Afina-wow [57]
1.  Factoring a quadratic expression ax2 + bx + c, where a ≠ 1, is different from factoring x2 + bx + c because for the former type of expression you have to factor out the value of "a". Then, proceed to the factoring steps as usual.

2. To confirm the equations to be equal with the parent function we do as follows:
<span> (2x – 4)(x + 5) = 2x^2 + 10x - 4x - 20 = 2x^2 + 6x -20
</span><span>(x – 2)(2x + 10) = 2x^2 +10x - 4x -20 = 2x^2 +6x - 20

3. The roots of the quadratic expression represents the values of x that would satisfy the expression. The x-intercepts are the values of x when y is equal to zero, it is where the plot touches intersects the x-axis.</span>

Answer:

3 / 5

Step-by-step explanation:

Favourable outcomes -> 2, 4, 5, 6, 8, 10, 12, 14, 15, 16, 18, 20

Number of favourable outcomes = 12

Total number of possible outcomes = 20

P (multiple of 5 or 2) = Number of favourable outcomes / Total number of

                                    possible outcomes

                                  = 12 / 20

                                  = 3 / 5

Hope it helps :)
