Step-by-step explanation:
f(x) × g(x)
= (x2 + 5x )× (3x2 -4x )
=3x4 + 15x3 - 4x3 -20x2
3x^4 + 11 x3 - 20x2
Exponent rule : a^-x = 1/a^x
x^-9 * x^-2 =
1/x^9 * 1/x^2 = (when multiplying exponents with same base, add exponents)
1/x^(9 + 2) =
1/x^11
The answer is 3,900 sq ft
The mother is 25 years old and the Daughter is 7 years old.
The slope is 0!! any horizontal line, like y = 1, y = 2, y = any other number, has a slope of 0. because it's a horizontal line, it's flat, so there isn't any incline or decline. just as a note: vertical lines (x = 1, etc.) have an undefined slope.
