First, X^2 while x is 4 =4^2, which is 4x4, which is 16
3X while x is 4 is 12. 16-12=4. So the answer is 4
Answer:
After solve the equations we get value of k=3
Step-by-step explanation:
We need to find value of k for which the lines x+2y=0, 3x-4y-10=0 and 5x+ky-7=0 are concurrent.
If the lines are concurrent, they pass through same point.
Let:

First solving equation 1 and 2 to find values of x and y
From eq(1) we find value of x and put it in eq(2)

After solving we get value of y=-1
Now putting in eq(1) to get value of x

So, Value of x= 2
Now put value of x=2 and y=-1 into eq(3) to find value of k

So, After solve the equations we get value of k=3
Answer:
6x² - 2x - 6
Step-by-step explanation:
note (f - g)(x) = f(x) - g(x), thus
f(x) - g(x)
= 6x² - 4 - (2x + 2) ← distribute
= 6x² - 4 - 2x - 2 ← collect like terms
= 6x² - 2x - 6
