Answer: 15
Step-by-step explanation:
By the trapezoid midsegment theorem,
Answer: She needed 144 square feet of carpet.
Step-by-step explanation:
Given : Maria is buying new carpet. Her bedroom is in the shape of a square.
The length of each side is 12 feet.
We know that the area of square =
So , the area of the bedroom = [which is an exponential expression]
Simplify it
The area of the bedroom =
Also, the carpet she needed = Area of the bedroom.
Thus , She needed 144 square feet of carpet.
The answer is 7 remainder 2.
The general equation given is x^2 - 4x + y^2 = -3. Transform this to an equation of a circle of the form x^2 + y^2 = r^2.
Use completing the square method:
x^2 - 4x + 4 + y^2 = -3 + 4
(x - 2)^2 + y^2 = 1
the center of the circle is (2,0) and r = 1
To check if it intersects the y axis, find the value of the x-intercept.
