Answer:
x = 24
Step-by-step explanation:
27 x 4 = 108
18 x 3 = 54
9 x 2 = 18
108 - 54 + 18 = 3x
72 = 3x
72/3 = x
24 = x
"Of the gravy" lol
To find the x-intercepts, you make f(x) = 0 and solve for x by setting each factor equal to 0.
0 = x(x + 1)(x - 5)(x - 7)
x = 0
x + 1 = 0
x = - 1
x - 5 = 0
x = 5
x - 7 = 0
x = 7
Your x-intercepts are x = - 1, 0, 5, 7
OR
There are x-intercepts at (- 1, 0), (0, 0), (5, 0), and (7, 0).
Answer:
260 square feet
Step-by-step explanation:
The area of a rectangle is given by the formula ...
A = LW
The area of two same-size rectangular rooms will be double the area of one of them.
__
<h3>room area</h3>
Each room has an area of ...
A = LW = (13 ft)(10 ft) = 130 ft²
<h3>carpet order</h3>
The order for carpet must be for 2 times the area of one room:
carpet order = 2 × 130 ft² = 260 ft²
Jerry should order 260 square feet of carpet.
Ay^2+2ay-3a
a(y^2+2y-3)
a(y-1)(y+3)
