Answer:
A = π(7x + 3)² cm²
Step-by-step explanation:
A = πr² is the appropriate equation. If r = 7x + 3 cm, then the area of this particular circle is:
A = π(7x + 3)² cm²
This should be easy because we just have to use substitution method. Substitute the value of x from the second equation into the x of the first equation.
-4(2y) + 11y = 15
-8y + 11y = 15
3y = 15 ; y = 5
Substitute this value of y to either the first or second equation.
x = 2(5) = 10
The ordered pair is therefore (10,5).
Answer:
I am not sure what the P is.
2,300,000,00. X 5% = $115,000,000. Commission
Step-by-step explanation:
(c+8)(c-8)
3(2y+5)(2y-5)
There are no like terms so it's still ab^2-b
