Answer
W=7
Explanation:
The formula for the perimeter for a rectangle is P = 2L + 2W
The formula for the area of a rectangle is A = LW
where L = length and W = width
P = 22 and A = 28
22 = 2L + 2W
28 = LW
Rewriting the 2nd equation L = 28/W
Substituting this into the first equation
22=2(28/W) + 2W
Reworking the equation to eliminate the denominator
22W = 2(28) + 2W2
22W = 56 + 2W2
and
2W2 - 22W + 56 = 0
Dividing by 2
W2 - 11W + 28 = 0
(W-7)(W-4)
Set each factor equal to 0 and solve each for 0
W = 4, W = 7
then W = 4

Please factor/simplify the following term
x^4-16
Answer:
x - 2Step-by-step explanation:
We will find the fourth root of both sides, which for x⁴ is simply going to be 4. For the other side, we will need to find the 4th root of 16. This can found in one of two ways.
Take the square root of 16, which and 4, and square root it again to get 2.
Use the calculator to find the 4th root of 16, which also comes out to be 2.

Answer:
132°
Step-by-step explanation:
y°=7x+20° (vertically opposite angles)
3x°+7x°+20°=180° (interior angles, since M is parallel to N)
10x+20°=180°
10x=180°-20°
10x=160°
x=16°
y°=7(16°)+20°
y°=112°+20°
y°=132°

Step-by-step explanation:
To eliminate the y terms and solve for x in the fewest steps, by which constants should the equations be multiplied by before adding the equations together?
First equation: 4x − 3y = 34
Second equation: 3x + 2y = 17
The first equation should be multiplied by 2 and the second equation by 3.
The first equation should be multiplied by 2 and the second equation by −3.
The first equation should be multiplied by 3 and the second equation by 4.
The first equation should be multiplied by 3 and the second equation by −4.
The possible answer is the first choice because thats how you do a equation
The first equation should be multiplied by 2 and the second equation by 3 and then we can add since the sign are different,.

When graphing on the complex plane, which
quadrant will the complex number10 – 13i be
found in?
Given :
A complex number z = 10 - 13i .
To Find :
Which quadrant will the complex number (10 - 13i) be found.
Solution :
Coefficient of real part of complex number, r = 10.
Coefficient of imaginary part of complex number, i = -13.
Since, the coefficient of imaginary part is -ve and real part is +ve .
Therefore, the complex number is in 4th quadrant.
Hence, this is the required solution.
When graphing on the complex plane, the complex number will be in the 4th quadrant.
The standard form of expressing complex numbers is expressed z = x + iy
x is the real axis (x-axis on the coordinate point)
y is the imaginary axis (y-axis on the coordinate plane)
Given the complex number z = 10 - 13i, this shows that the imaginary axis is a negative value while the real axis is a positive value.
This shows that when graphing on the complex plane, the complex number will be in the 4th quadrant.
