B = 12 - a
Subtract a from both sides to isolate b, and you get the answer.
If you are given the measure of each interior angle (162 degrees) of a regular polygon. how many sides does the polygon have? If you look at a pentagon first where the interior angle is 108 deg then you see. The angle at the center is 180-162=18 deg and 360/18=20 so the polygon has 20 sides.
Hope this helps you !!
Answer:
Since that is a quadratic equation, it will have 2 "x" intercepts.
x^2+7x+2
a = 1 b = 7 c = 2
You would solve for "x" using the quadratic formula.
x = [ -b +- sq root (b ^ 2 - 4 a c) ] / 2 a
x = [ -7 +- sq root (7^2 - 4*1*2) ] / 2 * 1
x = [ -7 +- sq root (49 -8) ] / 2
x1 = [-7 + 6.4031242] / 2
x1 = -.29844
x2 = [-7 - 6.4031242] / 2
x2 = -6.7016

Answer:
(-4,5) Quadrant II
Step-by-step explanation:
1) Think of drawing the letter C, starting at the upper right of the Quadrant to identify Each Quadrant, and Doing so will help knowing where Point C is.
2) After that identifying the point is simple X coordinate is Horizontal and Y coordinate is vertical X come before Y.
3) your answer will be (-4,5) Quadrant II

Volume of any cylinder = π times (radius)² times (height or length)
Radius of your cylinder = 1/2 of the diameter =5 cm
Volume = π (5 cm)² (14 cm) = 350 π cm³ = 1,099.56 cm³ (rounded)
