Uh sure what type of cereal?
1. Let's call:
x: the width of the walkway.
b: 2x+16 (there is a widht "x" of the walkway on each side).
h: 2x+32 (there is a widht "x" of the walkway on each side).
A: 924 ft^2 ( the area of the pool of including the walkway).
2. The area of a rectangle is:
A=(b)(h)
b: the base of the rectangle (2x+16)
a: the height of the rectangle (2x+32)
3. Then, we have a quadratic equation:
924=(2x+16)(2x+32)
4x^2+64x+32x+512-924=0
4x^2+96x-412=0
4. We apply the quadratic formula to find the value of "x":
x=(-b±√(b^2-4ac))/2a
x=3.71
The answer is: The width of the walkway is 3.71 ft
Answer:
3/4
Step-by-step explanation:
plug values in for x till you get it right
Well here's your answer straight <u><em>he must pay 29.82$ </em></u>and here's my work,
- 20% of 35 is 7 and since its 20% off we must subtract 35-7=28
- Next it said there's a 6.5 tax so that means we are adding on to 28$
- 6.5 of 28 is 1.82 so we add 28+1.82 which equals your answer 29.82
