There are 2 x’s so it’s 2x^2 + 9x because 2x4 is 8 + 1 x and then + 4 because you connect like terms so it would be 2x^2+9x+4
Answer:
the k value is 6
Step-by-step explanation:
The form of a qruadratic equation is f(x)=a(x-h)^2 + k, so by comparing this to the function f(x)=-18(x-2)^2 + 6 we can see that K = 6, a = -18,and h = 2.
Answer:
x=6
Step-by-step explanation:
10+2=5x-3x
12=2x
x=6
Let x = the larger number
Let x - 17 = the smaller number
x + x + 17 = 41
2x + 17 = 41
2x = 58
x = 29
x - 17 = 29 - 17 = 12
