Idont understand this question, me

2(x²+7x-7)

did it help?

Step-by-step explanation:

7x²+4x-9-5x²=10x-5

2x²+14x-14

2(x²+7x-7)

-2x^2 + 6x + 4

Step-by-step explanation:

We are subtracting  whole of 7x^2 + 4x - 9) so we put it into parentheses. So we have:-

5x^2 + 10x - 5 - (7x^2 + 4x - 9)

First distribute the negative over the parentheses

= 5x^2 + 10x - 5 - 7x^2 - 4x + 9

Now bring like terms together and simplify:-

= 5x^2 - 7x^2 + 10x - 4x - 5 + 9

= -2x^2 + 6x + 4    (answer)

step-by-step explanation:

sdfghjkl; vbnm,

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
