Which expression is equal to (6x−4)(3x−1)?
Natali5045456 [20]

Answer:

(6x-4)(3x-1)  = 18x^2  - 18x + 4  is the required simplification.

Step-by-step explanation:

Here, the given expression is (6x−4)(3x−1).

By DISTRIBUTIVE PROPERTY of numbers:

A ( B + C ) =  AB + AC

Simplifying the given expression, we get:

(6x-4)(3x-1) = 6x(3x-1)-4(3x-1)\\= 6x(3x)  -1(6x)  -4(3x)  +4\\=18x^2  - 6x - 12x + 4\\18x^2  - 18x + 4

or, (6x-4)(3x-1)  = 18x^2  - 18x + 4

Hence the given expression is simplified.

A cheetah can run 70 mph. What is this speed in feet per hour
Rasek [7]
To answer this question you have to determine how many feet are in a mile and multiply it by 70. There are 5280 feet in a mile, so 5280 x 70= 369600. So he can run 369600ft in an hour. (im pretty sure lol, i feel like i may have misunderstood this question, are there any answer choices?)

Two students in your class, Tucker and Karly, are disputing a function. Tucker says that for the function, between x = –3 and x
Effectus [21]
The difference between Tucker and Karly's take is that Tucker's solution is analytical while Karly's is graphical. But both are correct either way. 

For Tucker's solution, let's say at x=-3 the value for y is 4, and at x=3, the value of y is still 4, then the average rate of change or slope is 0. Note that the slope of the curve is Δy/Δx. Since there is no change for Δy, the slope is zero.

For Karly's solution, even if the curve travels high or low but would have the same elevation of x=-3 and x=3, the average rate of change is still zero. It is actually just same with Tucker's but Karly just verbalizes her solution that was observed visually.
