X^2-2x-168=0(x-14)(x-12)=0x=14 or -12since we want a negative number, -12-12 -28
This is an algabraic problem, so we would use variables:
Length=x
Width=y
The length is four times the width, so
x=4y
Since the equation for perimeter is P= 2(x+y), you would instead substitute 4y for x, and 7 for the perimeter.
7=2(4y+y)
Simplify.
7=2(5y)
7=10y
y=7/10
Since y is 7/10, you would substitute 7/10 into the equation x=4y.
x=4(7/10)
x=14/5
So, the dimensions are 7/10 x 14/5.
Hope this helps!
Answer:
see the attachment for the graph
Step-by-step explanation:
The radius can be computed from the distance formula:
d = √((x2-x1)^2 +(y2-y1)^2)
d = √((7-5)^2 +(2-5)^2) = √(4+9) = √13
d ≈ 3.6056
The radius of the circle is √13, about 3.6056 units.

Step-by-step explanation:
<span>Let opposite ray be drawn for the base side ray of the given angle.
This gives angle 180° between these two rays.
Angle bisectors of the given angles 50°, 90°, and 150° make respectively half of these angles : 25° , 45° and 75° with the base ray.
Then measure of the angles between the bisectors of the given angles and the drawn opposite ray are 180°-25°=155°, 180°- 45° =135° and 180°- 75° = 105° respectively.</span>
