Answer:
74 cars
Step-by-step explanation:
14(2) + 4x = 324
28 + 4x = 324
4x = 296
x = 74
Answer:
384 inches²
Step-by-step explanation:
The surface area of a cube is found by using 6a².
6 = the number of sides in a cube
a = the given dimension (in this case, 8 inches long)
SA = (6)8²
SA = 6(64)
SA = 384

P = f*s
f +3s = 60
p = (60 -3s)*s = 3(20 -s)*s
This equation describes a parabola that opens downward. The roots of the equation are s=0 and s=20, so the axis of symmetry is s=(0+20)/2 = 10. That is, the vertex (maximum) will be found at s=10.
The second number is 10. The first number is 60-3*10 = 30.
The product is maximized when the first number is 30 and the second is 10.
Answer:
x(x - 4) = 12
x2 - 4x = 12
x2 - 4x - 12 = 0
(x - 6)(x + 2) = 0
x - 6 = 0
x = 6
If the length is 6, the width must be 2.

Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 4) ← 2 points on the line
m = 
= 
= 
= 2
The line crosses the y- axis at (0, 4 ) ⇒ c = 4
y = 2x + 4 → A
