Answer: 4w^2 + 28w.
Step-by-step explanation:
Width of the rectangle= 2w
Length if the rectangle= 2w+14
Area of a rectangle= length×width
= 2w(2w+14)
= 4w^2 + 28w
The area of the rectangular patio A(w) is 4w^2 + 28w.
Step-by-step explanation:
Equation of circle: (x + 2)² + (y - 2)² = r²
Radius of the circle is 3 (from -2 to 1).
Hence we have
(x + 2)² + (y - 2)² = 3² or (x + 2)² + (y - 2)² = 9.
Answer:
angle X < angle W < angle Y
Step-by-step explanation:
In a triangle, the order of the lengths of sides and their respective angles are related.
The respective side of the largest angle is the longest, the respective side of the smallest angle is the shortest and so on.
In this problem, YW < XY < XW
So, angle X < angle W < angle Y

Answer:
$31
Step-by-step explanation:
First, to find how much the total was after we coupon we have to multiply 32.20 by 0.10. when we do that we get 3.22. Since the coupon was a discount we subtract 3.22 from 32.20 to get 28.98. We then multiply 28.98 by 0,07 to find out how much the 7% tax is. When you do that you get 2.0286. Add that to 28.98 since the tax add to the price. When you do that your answer round up to $31.
