You can find the dimensions of the model and plug them into the formula for volume (length x width x height)

Which polynomial represents the area?

murzikaleks [220]

Answer:

A is the Answer.

Step-by-step explanation:

You multiply x with 2x ( Gives you 2x^2 ) then -1 with 2x ( Gives you -2x ) then -8 with x ( Gives you -8x ) then -1 with-8 ( Gives you +8 ), finally you add the two x's ( not x^2 ). Your fibal answer will be 2x^2 - 10x +8.

Hope this helps.

The combined land area of the countries A and B is 170,973 square kilometers. Country A is larger by 473 square kilometers. Det

MAVERICK [17]

$A+B=170,973$

A is larger by $47 km^{2}$

The equation is $(B+473)+B=170,973$

Subtract 473 from each side and add the B's

$B+473-473+B=170,973-473$

$2B=170,500$

Now divide the number by the variable.

$170,500$ ÷ $2=85,250$

$B=85,250$

To check, replace the B's with the value.

$(85,250+473)+85,250=170,973$

$85,723+85,250=170,973$

Answer:

County A= $85,723km^{2}$
County B= $85,250km^{2}$

Answer:

1. n + 8 = 10

2. $\frac{n}{12}$ = 10

3. 8n - 6 = 34

4. 3(n + 12) = 45

5. No

6. Yes

Step-by-step explanation:

(only for questions 5 and 6)

5. If you substitute in y = 1, you get 1 * 49 = 0 or 49 = 0 which is not true.

6. If you substitute in b = 8, you get:

$5(8-3)= 25\\5(5) = 25\\25 = 25$

this is true.

(20 POINTS PLS HELP!!)

Pie

B would be the right answer, because you can not only have one point to determine a line.A line segment goes to one point and stops and a line goes on infinitely
