Answer:
The zeros occur when x = -3 , -1 , 1 and 7
Step-by-step explanation:
I don't exactly know how to do this so I can show you how to do it using some sort of method of division. There are 2 huge steps to be taken. Start with 1
Using synthetic division you get
-1 || 1 - 4 -22 4 21
-1 5 17 -21
===================
1 - 5 -17 21 0
So far we have x = - 1 or (x + 1) is a factor.
It turns out by trial and error that x = - 3 is a factor. What you get after that synthetic division is x^2 - 8x + 7 which factors into (x - 7)(x - 1)
So what we get is
(x - 1)(x + 1)(x - 7 )(x +3)
Answer:
first option
Step-by-step explanation:
the area of a rectangle is
base*height
so the sum is
which is the first option
The solution is x = 2 and y = 4
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
y = 2x -------- eqn 1
x = -y + 6 ----------- eqn 2
We can solve the system of equations by substitution method
<em><u>Substitute eqn 1 in eqn 2</u></em>
x = -2x + 6
Move the variables to one side and constants to other side
x + 2x = 6
3x = 6
Divide both sides of equation by 3
x = 2
<em><u>Substitute x = 2 in eqn 1</u></em>
y = 2(2)
y = 4
Thus the solution is x = 2 and y = 4
Answer:
8 : 6
4 : 3
Step-by-step explanation:
Just simplify the fraction.
8 : 6
4 : 3
Answer:
the answer is 24
Step-by-step explanation:
times 4 by 7 to get 24 because we only need the botom of the prism so if their 1 inch by 1 inch then how many times can it fit in seven only seven times so times that by how long it is witch is four then you would get 24
