Answer:
+5x-36
Step-by-step explanation:
To multiply binomials there are 2 ways. F.O.I.L., or the box method.
I will use the box method, and I hope it helps you!
After looking at the picture, this is not the answer quite yet.
Subtract 4x from 9x.
9x-4x=5x
So, the answer will be +5x-36
Answer:
x^2 + 5x - 36
Step-by-step explanation:
Hello!
For this equation, we are going to multiply both binomials using FOIL.
FOIL stands for:
F irst
O utside/Outer
I nside/Inner
L ast
This tells you the order in which you multiply two binomials in parentheses.
Let's get started!
First: x * x = x^2
Outside: x * -4 = -4x
Inside: 9 * x = 9x
Last: 9 * -4 = -36
x^2 - 4x + 9x - 36
These problems usually involve combining like terms, which is what we have to do here: -4x + 9x = 5x
And there you have it!
x^2 + 5x - 36
If you have any questions, just comment!
Hope I helped!

Answer:
-2
Step-by-step explanation:
The leading coefficient in a polynomial is the coefficient that corresponds with the highest degree term. In this case, -2 is the leading coefficient since its term has x² as the highest degree of the quadratic.
8 thousands is equal to 8000. 15 hundreds is equal to 1500. 15 tens is equal to 150. 18 ones is equal to 18. So just add them up. 8000 + 1500 = 9500. 9500 + 150 = 9650. 9650 + 18 = 9668. The number is 9668
No. 0.158 is less than 0.58
Standard form is (y=x+n) *n=number* y=-3x+2
