Step-by-step explanation:
F(x) = (x + 7)³
= 3C0 * x³ + 3C1 * x² * 7 + 3C2 * x * 7² + 3C3 * 7³
= x³ + 21x² + 147x + 343.
Answer:
63
Step-by-step explanation:
A=(h(b)b)/2
A=w x l
Answer:
2
Step-by-step explanation:
2/3x + 8/3 = 2x
multiplicate each by 3 : 2x + 8 = 6x
Put all the x on the same side : 8 = 4x
divide each by 4 : 2 = x
x = 2
Answer:
undefined
Step-by-step explanation:
A line with a slope of zero is a horizontal line parallel to the x- axis
Thus, a line perpendicular to it is a vertical line parallel to the y- axis, with an undefined slope.
