π r³
Answer: 99
Step-by-step explanation:
10x-9=9x
-9=-x
x=9
angle 7 = 9*(9)=81
angle 6 = 180-81= 99
NOTE: DO NOT hit 90 because I did that and got it wrong. Just a heads up. Get luck!
Answer:
8x²+5x+1
Step-by-step explanation:
3x²-5x+12
5x²+ x - 11
________
3x²+5x²= 8x²
}
5x+x =5x
}
12-11 =1
=
8x²+5x+1
Hey there!
Let's first define our goal. Our goal here is to be able to isolate the variable, n, and solve for it by moving everything to the other side. We see that we have two sides of the equation, and by using the property of equality which states that whatever you do to one side you do to the other and the expression remains equal, we can solve this equation.
It looks like the only thing we have on the left side with n is that 6 1/2. In order to get rid of it, we must subtract it from both sides, because the property of equality states you must do the inverse operation.
We have:
n = 12 - 6 1/2
n = 5 1/2
Hope this helps!
Answer:
(x + 1)(x + 4)
Step-by-step explanation:
We want to factor x² + 5x +4 into two binomial factors. Note that 1*4 = 4 and that 1 + 4 = 5, so:
y = x² + 5x +4 = (x + 1)(x + 4)
