Answer:

135x^3 + 3x^2 - 46x + 8.

Step-by-step explanation:

(5x-1)(3x+2)(9x-4)

= (5x - 1)(27x^2 + 18x - 12x - 8)

=  (5x - 1)(27x^2 + 6x - 8)

= 5x(27x^2 + 6x - 8) - 1(27x^2 + 6x - 8)

= 135x^3 + 30x^2 - 40x - 27x^2 - 6x + 8

= 135x^3 + 3x^2 - 46x + 8.

Step-by-step explanation:

= ( 5x - 1 ) ( 3x + 2 ) ( 9x - 4 )

= 5x ( 3x + 2 ) - 1 ( 3x + 2 ) ( 9x - 4 )

= 15x² + 10x - 3x - 2 ( 9x - 4 )

= ( 15x² + 7x - 2 ) ( 9x - 4 )

= 15x² ( 9x - 4 ) + 7x ( 9x - 4 ) - 2 ( 9x - 4 )

= 135x³ - 60x² + 63x² - 28x - 18x + 8

= 135x³ + 3x² - 46x + 8

PLEASE HELP DON’T ANSWER IF YOU DON’T KNOW!! Mr. Sanchez drives 120 miles in 3 hours. At the same rate, how far will he drive
anygoal [31]

Answer:

200 miles

Step-by-step explanation:

First have to find how many miles he drives in 1 hour. So, we divide 120 miles by 3 hours, since we assume that he managed to drive an equal amount in each hour.

120/3=40

This shows that Mr. Sanchez drove at a rate of 40 mph.

But, this isn't the answer. 40 miles is the distance for one hour of driving. To find the distance for 5 hours, we have to multiply the distance by 5 as well.

40 times 5=200
