Answer:
Step-by-step explanation:
Take the area of the yard and subtract from it the area of the pool. In quadratic form, the area of the pool is

Subtracting the area of the pool from the area of the yard:

Since the negative in front of the parenthesis will change the signs inside:

Combine like terms to get the area left after the pool goes in:

Having the angle in radians and the diameter of the circle we can easily calculate the length using the following expression
Length = angle(radians)*diameter/2
With this expression we can easily deduce the perimeter of a circle (length of the full arc)
Length = Perimeter = 2*pi*r
There is only one operation involved in this process
<span>We are asked to find a term that describes the expressions 4(3+2) and 4(3)+4(2). The said expression conforms to one of an algebra property called distributive property. Distributive Property simply distribute the first term to the two or more terms inside a parenthesis. This property helps in simplifying an expression.</span>
Answer:
x = -3
Step-by-step explanation:
5 x + 3 = 4 x
Solve for x
5x - 4x + 3 = 0
x + 3 = 0
x = -3
