Erik made an error in his homework. He said that
3x + 12 + 4x2 - 3 is equivalent to 7x + 9.
What is the correct way for Erik to fix his error?
A) He should combine 12 and 3 to get 15.
B) He should combine 3x and 4x² to get 7x3.
C) He should not combine 3x and 4x?.
D) He should not combine 12 and 3.

C) He should not combine 3x and 4x^2

Step-by-step explanation:

3x + 12 + 4x^2 - 3

You cannot combine 3x and 4x^2

0.6

39mph

step-by-step explanation:

(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.
