Answer:
x =12
Step-by-step explanation:
Since this is an isosceles triangle the angles at the bases of the equal sides are equal
The unmarked angle is 4x
The 3 angles of a triangle total 180 degrees
4x+4x+ 84 =180
Combine like terms
8x +84 = 180
Subtract 84 from each side
8x +84-84 = 180 -84
8x =96
Divide by 8
8x/8 = 96/8
x =12
Answer:
$150
Step-by-step explanation:
Find how much Nicole earns for 3 hours by plugging in 3 as h in the function:
E(h) = 50h
E(3) = 50(3)
E(3) = 150
So, for tutoring for 3 hours, Nicole will earn $150
Answer:
Width=6 Length=36
Step-by-step explanation:
The stage is rectangular since the length is not equal to width.
We use the formula (Width × Length) to obtain the area of any rectangle.
But the Length is 6 times the Width, therefore we equate the formula for the area of stage as
Width × 6Width = 216
we get Width as 6 and 6width which is the length as 36
(3 + 6i)(3 + 7i)
FOIL: First, Outside, Inside, and Last
3 x 3 = 9
3 x 7i = 21i
6i x 3 = 18i
6i x 71= 42i
9 + 21I + 18I + 42I = 9 + 81I
a = 9
B = 81I
