Answer:
the answer is 47
Step-by-step explanation:
If x equals the number, then seven times the number is 7x; three less than that is 7x-3.
Answer:
The length of the intercepted arc for circle S is (1/2)π ft
Answer:
so we get as,
let, y = 2 - 9i
so the absolute value is |y|
so we get as,
|y| =
2-9i
so the absolute value is |y|
|y|=√
2 to the 2nd power plus 9 to the second power
so we get as,
|y|=
√81+4=√85
so the value is √85

Answer:
x = 13
Step-by-step explanation:
isosceles trapezoid
x^2 - 5 + x + 3 = 180
x^2 + x - 2 = 180
x^2 + x - 182 = 0
(x + 14)(x - 13) = 0
x + 14 = 0 ; x = -14
x -13 = 0; x = 13
Angle can't be negative so answer is x = 13
