Answer: x = 10;
Both the angles are congruent, therefore;
8x - 12 = 6x + 8
=> Now subtract 6x from each side of "="
2x - 12 = 8
=> Add 12 to each side;
2x = 20
=> Lastly divide each side by 2;
<u>x = 10</u>
Hope this helps!
The answer is a because you multiple times and divided
(42)^3 -(24)^3 - (18)^3
= (74,088)-(13,824)-(5,832)
= 54,432
Answer:
Equation of parabola is: 
Step-by-step explanation:
By plotting a rough graph with the values given we get an opening upward parabola.
Standard equation for a parabola opening upwards is given by:

We can solve for a,b,c by substituting the given values of x and y.
Putting x=0 and y=-6 in the above equation,we get:
c = -6
Putting x=-2 and y=4, we get:
---------1
Putting x=4 and y=70, we get:
--------2
Solving equation 1 and 2, we get
a=4 and b=3
Hence
