Step-by-step explanation:
Factor {x}^{3}-7x-6x3−7x−6 using Polynomial Division.
({x}^{2}-x-6)(x+1)(x2−x−6)(x+1)
2

Factor {x}^{2}-x-6x2−x−6.
(x-3)(x+2)(x+1)(x−3)(x+2)(x+1)
Answer:
7 meters
Step-by-step explanation:
Circumference is equal to pi times diameter. If you divide both sides of the equation by pi you get diameter of the Big Ben clock. If you divide diameter by 2 you get radius.
Answer: She had 16 boxes of pencils.
Step-by-step explanation: Divide 96 by 6 to get 16.
In this problem “like terms” has two groups: one with a number and y, and one with just numbers. First I’ll rewrite the equation with the terms in a different order, grouped with like terms. Then we’ll do the math for them:
7y + 10 + 3y - 4 - 6y
= 7y + 3y - 6y + 10 - 4
= 10y - 6y + 6
= 4y + 6
Let me know if you have questions on this.
Answer:
Denote O as center of circle, draw OA, OC.
As property of tangent line from outside of circle (angle OAD = angle OCD = 90 deg):
=> AOC + D = 180
Moreover, angle AOC = 2 x angle B = 2 x 65 = 130
=> D = 180 - 130 = 50 deg
Hope this helps!
