Answer:
no it is not
Step-by-step explanation:
<span>Write the problem: 12ds/w = cd </span>
Divide each side by 'd': 12s/w = c
Multiply each side by 'w' : 12s = cw
Divide each side by 'c' : 12s/c = w

Answer:
C.
f(x) = 8*(x - 1)²
f(x) = 8x² - 16x + 8
Step-by-step explanation:
vertex form:
f(x) = a*(x - h)² + k
where (h, k) is the vertex of the parabola
In this case, the vertex of the parabola is at (1, 0). Replacing this information into the equation we get:
f(x) = a*(x - 1)²
The parabola passes through point (2, 8). Replacing this information into the previous equation we get:
8 = a*(2 - 1)²
8 = a
Then, the final equation is:
f(x) = 8*(x - 1)²
Expanding the quadratic term and applying distributive property:
f(x) = 8*(x² - 2x + 1)
f(x) = 8x² - 16x + 8
Answer:
l = 24ft
Step-by-step explanation:
A = lw
360 = (x + 9)(x)
360 = x^2 + 9x
0 = x^2 + 9x - 360
0 = (x + 24)(x - 15)
x ≠ -24 (length cannot be negative)
x = 15
l = 15 + 9
l = 24ft
