Answer:
40x = 2,000
x = 50
Step-by-step explanation:
to find x of the equation 40x you first want to try different number until you get 2000 and in 40x it says you must multiply meaning 40 times a number equals 2000 and 40 times 50 equals 2,000 making x = 50
finding x:
40x - this means to multiply
40/x - this means to divide
40 - x or x - 40: this means to subtract
40 + x or x + 40: this means to add
Answer:
f(x) = x⁴-6x³-13x²+66x+72
Step-by-step explanation:
Factors are: (x+3)(x+1)(x-4)(x-6)
[(x+3)(x+1)][(x-4)(x-6)]
[x²+3x+x+3][x²-4x-6x+24]
(x²+4x+3)(x²-10x+24)
x⁴+4x³+3x²-10x³-40x²-30x+24x²+96x+72
f(x) = x⁴-6x³-13x²+66x+72
