Maggie would be 6
6•3=18
18-4=14
14+6=20
Answer:
<h2>x = 3 and x = 4 → (3, 0) and (4, 0)</h2>
Step-by-step explanation:
Answer:
difference in area = 16 ft²
if you use 8 the difference in length between Jack patio and his neighbor patio will be will be 15 - 13 = 2 ft
if you use 13 the difference i length will be 25 - 18 = 7 ft
Step-by-step explanation:
Jacks rectangular patio
width = a
length = 2a - 1
area = lw
where
l = length
w = width
area = 120 ft²
a(2a - 1)
2a² - a - 120 = 0
(a - 8) (2a + 15)
a = 8 or -15/2
Ron's rectangular patio
width = a
length = a + 5
area = lw
area = 104 ft²
a (a + 5) = 104
a² + 5a -104 = 0
(a + 8) (a - 13)
a = -8 or 13
How many square feet longer is jack patio longer than Ron's patio is the difference in their area. Therefore,
120 - 104 = 16 ft²
The value 8 or 13 can be used for a since the width a have to be the same.
if you use 8 the difference in length between Jack patio and his neighbor patio will be will be 15 - 13 = 2 ft
if you use 13 the difference i length will be 25 - 18 = 7 ft
3 1/2 is less because 1 liter in cups is 4.227
<span>3x^2 - 4 = 7x is the standard form. To get standard form into quadratic you must have one side of the equation equal zero. The easiest way to so is subtracting 7x on both sides of the equation.
</span><span>3x^2 - 4 = 7x
-7x -7x
3x^2 -7x - 4 = 0
So, </span>3x^2 -7x - 4 = 0 is the quadratic form.
