Ok so if we call the width x then the length is 2x-7
Now by adding a 5 foot brick border around the edge the new dimensions are:
x+10 and 2x+3
Now we can form an equation to solve:
(x+10)(2x+3)=195
2x²+23x+30=195
2x²+23x-165=0
Now we can solve this for x
(2x+33)(x-5)=0
So x=-33/2 or x=5
As x cannot be less than 0 x must be equal to 5
So the dimensions of the garden are 5 feet by 3 feet
Answer:
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex ad a is a multiplier
Here (h, k ) = (8, - 1 ) , then
y = a(x - 8)² - 1
To find a substitute (0, - 17 ) into the equation
- 17 = a(0 - 8)² - 1 ( add 1 to both sides )
- 16 = 64a ( divide both sides by 64 )
= a , that is
a = - ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
y = -
(x - 8)² - 1 ← equation of parabola
