Multiply the Polynomials: (2x+3) (-x+2y-4)

Mathematics
1 answer:
GREYUIT [131]1 year ago
3 0

The result of multiplying the polynomials is (2x + 3) (-x + 2y - 4) = -2x² + 4xy - 11x + 6y - 12

<h3>How to multiply the polynomials?</h3>

The polynomial expression is given as

(2x + 3) (-x + 2y - 4)

Expand the brackets in the above polynomial expression

So, we have

(2x + 3) (-x + 2y - 4) = 2x * (-x + 2y - 4) + 3 * (-x + 2y - 4)

Open the brackets in the above polynomial expression

So, we have

(2x + 3) (-x + 2y - 4) = -2x² + 4xy - 8x + -3x + 6y - 12

Evaluate the like terms in the above polynomial expression

So, we have

(2x + 3) (-x + 2y - 4) = -2x² + 4xy - 11x + 6y - 12

Hence, the solution is -2x² + 4xy - 11x + 6y - 12

A farm processes 6,000 gallons of milk every hour. Which equation represents the amount of milk, y, that the farm processes in x
Free_Kalibri [48]

Answer:

c

Step-by-step explanation:

if y is equal to the amount of milk and 6000 gallons are made an hour then you have to multiply the amount of hours(x) by the 6000 gallons of milk made in 1 hour so y=6000x

Please help me with this..
AleksandrR [38]

Answer:

f = 1

Step-by-step explanation:

Use the method of cross- multiplication

\frac{a}{b} = \frac{c}{d} ⇒ ad = bc, thus

20f = 5(f + 3) ← distribute

20f = 5f + 15 ( subtract 5f from both sides )

15f = 15 ( divide both sides by 15 )

f = 1

Maureen earned some money doing odd jobs last summer and put it in a savings account that earns 9% interest compounded quarterly
ivolga24 [154]

Answer:

Maureen earned $123.19 doing odd jobs

Step-by-step explanation:

The compound interest formula is given by:

A(t) = P(1 + \frac{r}{n})^{nt}

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit year and t is the time in years for which the money is invested or borrowed.

In this question:

Compounded quarterly means that n = 4

10 years, so t = 10

9% interest, so r = 0.09

There is $300.00 in the account, which means that A = 300

How much did Maureen earn doing odd jobs?

This is P.

A(t) = P(1 + \frac{r}{n})^{nt}

300 = P(1 + \frac{0.09}{4})^{4*10}

(1.0225)^{40}P = 300

P = \frac{300}{(1.0225)^{40}}

P = 123.19

Maureen earned $123.19 doing odd jobs

Question 1 of 10
Sonbull [250]

The statement regarding the expansion of (x + y)" that is correct is D. The coefficients of yn - 1 and yn – 1 both equal 1.

<h3>How to expand?</h3>

It should be noted that for any positive integer, n, the expression of (x + y)^n will be C(n,0)x^n + C+n, 1)x^n-1 .... C(n, n)y^n.

Here, the statement regarding the expansion of (x + y)" that is correct is that the coefficients of yn - 1 and yn – 1 is both equal to 1.
