ivann1987 [24]

Answer:

$-12a^{4} + 3a^{3} + 20a^{2} -5a$

Step-by-step explanation:

$(5a-3a^{3} )$ • $(4a-1)$

Let's use FOIL (first, outer, inner, last) to solve this. We'll multiply the terms by one another in that fashion.

$20a^{2} - 5a - 12a^{4} + 3a^{3}$

Rearrange in decreasing exponents.

$-12a^{4} + 3a^{3} + 20a^{2} -5a$

Rhonda bought five shirts from a

densk [106]

Answer:

Option C $10+5x=24+3x$

Step-by-step explanation:

Let

x ------> the cost of each shirt

we know that

The cost of 5 shirts plus $10 (amount of money that would remain) must be equal to the cost of 3 shirts plus $24 (amount of money that would remain). Considering that the cost of the shirts is the same

The linear equation that represent this scenario is

$10+5x=24+3x$

Solve for x

$5x-3x=24-10$

$2x=14$

$x=\$7$

A? ________ is an arrangement of r objects chosen from n distinct objects without repetition and without regard to order

aliya0001 [1]

If we do not care about order, then a combination is an arrangement of r objects chosen from n distinct objects. It can often be seen written as:

$^{n}C_r$ or $\left(\begin{array}{cc}n\\r\end{array}\right)$

Its factorial form is:

$^{n}C_r = \frac{n!}{r!(n - r)!}$

if a taxi charges $3.50 for the first on-fifth of a mile, then $0.55 cents for each additional one-fifth mile, how far can one t

34kurt

Let's forget for the tie being the cost ($3.5)of the 1st fifth of a mile:

Taxi charge excluding $3.5, is $13.95 - $3.5 = $10.45.

If each of the 5th (1/5) of a mile costs $0.55, then with $10.45 we can drive:
10.45/0.55 = 19 fifth of a mile. Add to that the 1st fifth = 20 fifth of a mile
20 fifth = 20 x 1/5 = 4 miles (answer)

Why is 4b-7-3b+9 equal to b+2

rodikova [14]

The first expression can be simplified by combining like terms.

First, the terms "4b" and "-3b" can be combined to form "b"
Then, the terms "-7" and "9" can be combined to form "2"

Finally, we simply put these two final terms together, to form "b+2"

Hence, 4b-7-3b+9 is equal to be + 2.

Hope this helps!
