Answer:
x = 12
Step-by-step explanation:
The square of the length of the tangent segment is equal to the product of lengths from the external common point to the two circle intersections of the secant.
x^2 = (2)(70+2)
x^2 = 144
x = √144
x = 12
Answer:
a(10 - 13)
Step-by-step explanation:
The only common factor between these numbers is a, as 10 and 13 do not share factors (13 is prime). We can only factor out a.
You'd move the decimal to the right twice so 0.0514 as a percentage is <span>5.14%</span>
Answer:
Step-by-step explanation:
let the first piece=x ft
second piece=2 x ft.
third piece=6 x ft.
x+2x+6x=180
9 x=180
x=20
first piece=20 ft.
Replace a and b in the equation with their values given:
-0.5(7(-6)-12(-10)-(8.4(-10)-14(-6))
Multiply within the parentheses
-0.5(-42 + 120) -(-84 + 84)
Add inside the parenthesis:
-0.5(78)-0
Multiply:
-.05 x 78 = -39
The answer is -39
