Answer:

it is A

Step-by-step explanation:

you need to distribute the terms $3x^2$ and -4 into their respective parentheses.

$3x^2*x =3x^3$

$3x^2*3=9x^2$

so the left side completed is $3x^3+9x^2$

next do the other side

$-4*1 =-4$

$-4*-2x^2 =8x^2$ (remember - * - = +)

Right side complete is $-4+8x^2+7$

both put together is $3x^3+9x^2-4+8x^2+7$

combine like terms to get

$3x^3+17x^2+3$

Answer:

The probability is $\frac{16}{43}$

Step-by-step explanation:

The psychology class has 9 freshman male, 15 freshman females, 8 sophomore male and 12 sophomore female.

Total population constitution of the class=

17 males and 27 females and 44 students in total.

If on selecting on the first attempt, a male has been picked up then the number of males for the picking up in the second attempt has to decrease by one.

Also, the total number of students from which it has to be selected also decreases by 1, because one child has already been selected.

Therefore for Second Attempt, Total 43 students and 16 males.

Probability= $\frac{No.OfFavorableOutcomes}{TotalNo.OfOutcomes}$

Probability= $\frac{16}{43}$

A video game store allows customers to rent games for $4.75 each. Customers can also buy a membership for $54 each year, and vid

Nezavi [6.7K]

Answer:

Step-by-step explanation:

Cost of membership + game = 2.50x + 54

Cost of just games = 4.75x

The catch is, how do we make up the 54 dollars?

So equate the 2 costs

4.75x = 2.50x + 54 Subtract 2.50

4.75x - 2.50x = 54 Combine

2.25x = 54 Divide by 2.25

x = 54/2.25

x = 24

That means that 24 is the break even point.

Answer:

[c] The value of w cannot be a negative number.

[d] Substitution is used to replace the variable l with a value of 20.

[e] The subtraction property of equality is used to isolate the term with the variable w.

Step-by-step explanation:

To figure out which steps of the solution are true, let us solve.

2 l plus 2 w equals 62 -> 2l + 2w = 62

----

2l + 2w = 62

2(20) + 2w = 62 <- Substitution is used to replace the variable l with a value of 20.

40 + 2w = 62

2w = 22 <- The subtraction property of equality is used to isolate the term with the variable w.

w = 11

This means that the value of w is not 10 feet so the first option is incorrect. This shape is a rectangle, so the value of w cannot be 0. Since we cannot have a negative measurement, option three is incorrect. This leaves us with the last three options as our answer, shown by the work above.

The distance traveled is equal to the rate of speed multiplied by the time traveled. if the distance is measured in feet and the

fgiga [73]

The rate of time is measured in feet per minute.
Because distance = rate * time, 
Then rate = distance / time, which gives you feet / min.
