A. Ten seconds is your answer
Answer:
x= 65 z= 38 y= 77
Step-by-step explanation:
x=65° (opposite angles are equal)
z= 180°-[71+71 (bc the other side is also equal to 71)]
z= 180°-142°=38°
y= 180 - [sum of angle x (65°) and angle z (38°)]
y= 180 - 103= 77°
to make sure ur answer is correct the sum of angle x, y and z MUST = 180
lets check:
65° + 38° + 77° = 180°

Put the given values of p and q in the factored form equation.
... f(x) = (x -(-1))(x -(-2)) . . . . p and q values put in
... f(x) = (x +1)(x +2) . . . . . . .simplified
<h3>2)</h3>
Multiplying the factors, we have
... f(x) = x(x +2) + 1(x +2) = x² +2x +1x +2
... f(x) = x² +3x +2

We want to factor x³ -x² -6x. We notice first of all that x is a factor of all terms. Thus we have
... = x(x² -x -6)
Now, we're looking for factors of -6 that add up to -1. Those are -3 and 2. Thus the factorization is ...
... = x(x -3)(x +2)

We want a description of the structure and an equivalent expression for
... 64x⁹ -216
We note that 64, 216, and x⁹ are all cubes, so this expression is ...
... the difference of cubes.
It can be rewritten to
... = 8((2x³)³ -3³)
and so can be factored as
... = 8(2x³ -3)(4x⁶ +6x³ +9)
the common difference is two of course
