Answer:
-10x⁶+20x⁵+4x⁴-46x³+16x²+12x-24
Step-by-step explanation:
(-5x³ + 2x - 4)(2x³ - 4x² + 6)
= -10x⁶ + 4x⁴ - 8x³ + 20x⁵ - 8x³ + 16x² - 30x³ + 12x - 24
= -10x⁶+20x⁵+4x⁴-46x³+16x²+12x-24
(-5x³ + 2x - 4)(2x³ - 4x² + 6)
Is same as
(2x³ - 4x² + 6)(-5x³ + 2x - 4)
Because multiplication is commutative.
a×b = b×a
Step-by-step explanation:
The instructor had saved $3,500 and rents an apartment for $275 monthly. The slope-intercept form of the above scenario is :
y=-275x+3500
The instructor belives that the point (6, 1850) would be on the equation of the line. Put y = 1850 and x = 6 in the above equation. So,
1850=-275(6)+3500
1850=1850
LHS=RHS
It means that the point (6,1850) lies on the line. Hence, he was correct.

Conjectures are conclusions formed from evidences. Steven's conjecture that:
is true because:
or
for ![|x| > 5](https://tex.z-dn.net/?f=%7Cx%7C%20%3E%205)
Given that:
![|x| > 5](https://tex.z-dn.net/?f=%7Cx%7C%20%3E%205)
Split the inequality as follows:
or ![x > -5](https://tex.z-dn.net/?f=x%20%3E%20-5)
Take the cube of both sides
or ![x^3 > -5^3](https://tex.z-dn.net/?f=x%5E3%20%3E%20-5%5E3)
Evaluate all exponents
or ![x^3 > -125](https://tex.z-dn.net/?f=x%5E3%20%3E%20-125)
