What is 2x to the 2 plus 5x minus 42

x = 4

Hope that helped. :)

Step-by-step explanation:

2x^2     +      5x   -    42   >  There is no like terms > already simplified.

Factor:

   2x^2     +     5x    -    42

=   (2x    -   7 ) ( x     +   6 )

Answer  =       (2x   -   7 ) ( x    +   6 )

Hope that helps    Have a wonderful evening    : )

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
