K(x) = 2x^2 + 7
What is k(4)

maybe this helps

Step-by-step explanation: k*(x)-(2*x^2+7)=0

STEP

1

:

Equation at the end of step 1

kx - (2x2 + 7) = 0

STEP

2

:

Trying to factor a multi variable polynomial

2.1 Factoring kx - 2x2 - 7

Try to factor this multi-variable trinomial using trial and error

Factorization fails

Equation at the end of step

2

:

kx - 2x2 - 7 = 0

STEP

3

:

Solving a Single Variable Equation:

3.1 Solve kx-2x2-7 = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

We shall not handle this type of equations at this time.

1; 35 is the ratio

step-by-step explanation:

d 600 because 15*10*2=300

300+300=600
