Answer:
2
Step-by-step explanation: 0 = 2x - 4
2x = 4
x = 2
Im not sure but i think its A because you have no value to multiply 3 so you just multiply it by itself.It would be a negative because you cant divide 3 by 2.so it would be A.-x9y2.
i hope i was correct and helped if not you can go ahead and delete my answer:)
The answer is 3 3x3x3=9
Hope this helped:)
First step is to factor. With a polynomial function in the form ax² + bx + c = f(x), we have to find what factors of term C have a sum of term B.
So with this, we need factors of -90 add up to become -1. Your factors are - 10 and 9.
f(x) = x² + 9x - 10x - 90
Now we group together and pull out GCFs.
f(x) = (x² + 9x) + (10x - 90)
f(x) = x(x² + 9) - 10(x + 9)
f(x) = (x - 10)(x + 9)
Now, set each factor equal to zero.
x - 10 = 0, x + 9 = 0
For the first equation you are going to add 10 to both sides to get x by itself. Subtract 9 from both sides in the second equation for the same reason.
x = 10, x = -9
Your zeros are at x = -9, 10 or at the ordered pairs (-9, 0) and (10, 0).
First you distributive property:
3x-15=9
Add 15
3x=24
Divide
x=8
