Answer:
x=10 or x=-4
Step-by-step explanation:
|x-3|=7
There are two solutions, one positive and one negative
x-3 = 7 and x-3 = -7
Add 3 to all sides
x-3+3 = 7+3 x-3+3 = -7+3
x = 10 x = -4
10√3 cm.
The radius of an incircle of a hexagon is the same measure as the apothem. find the apothem by taking half of the central angle and create a right triangle perpendicular to the side. The central angle is 60 so the angle opposite the side length will be 30. this creates a 30-60-90 triangle with the ratio x:x√3:2x. half the side opposite 30 is 10, so x=10. the base angle of the side is 60 so it will be x√3. plug in 10 for x to get 10√3 cm.

Answer:
x² - x - 12 = (x - 4)(x - 3)
Step-by-step explanation:
We have the trinomial x² - x - 12.
We have to show two binomials to be factors of this above trinomial.
For this first we have to factorize the trinomial.
Now, x² - x - 12
= x² - 4x + 3x - 12
= x(x - 4) + 3(x - 4)
= (x - 4)(x - 3)
So the binomials are (x - 4) and (x - 3) that are factors of the trinomial x² - x - 12. (Answer)
