Answer:
113.04ft
Step-by-step explanation:
Radius of circle + width of outer circle
15 + 3 =18ft
Circumference of the outer edge becomes
2 × 3.142 × 18
=113.04ft
Answer:9*(n+4)
Step-by-step explanation:
Product means multiply
sum means add
We do the sum first
Let n be the unknown number
sum of a number and 4.
(n+4)
now do the product
9*(n+4)
A) Sub g(x) and h(x) into the equation:
x^2 + 3x - 40 - (-x -3)
= x^2 + 3x - 40 +x + 3
= x^2 + 4x - 37
Find x:
x= 4.40 and x= -8.40
b) Sub f(x) and g(x) into the equation:
(x^2 - 64) / (x^2 + 3x -40)
= ((x+8) x (x-8)) / ((x+8) x (x-5))
= (x - 8) / (x-5)
Find x:
x= 8 and x = 5
How to get those number:
(x^2 - 64) = x^2 - 8^2 = (x-8) x (x+8)
( x^2 + 3x - 40) = (x^2 + +8x - 5x - 40) = x( x + 8) - 5( x + 8) = (x-5) x (x+8)
Try to do c and d :)
We just combine the terms, like this:
-8y = -12
The answer is: y = 1.5 or 3/2.
Hope this helped! c:
