31x^2 + 53x - 8

Use the FOIL method to find the area of the large rectangle. (7x - 2)(9 + 5x)

First term in each binomial: 7x * 9 = 63x
Outside terms: 7x * 5x = 35x^2
Inside terms: -2 * 9 = -18
Last term in each binomial: -2 * 5x = -10x

Now, just add them all up.

63x + 35x^2 - 8 - 10x

35x^2 + 53x - 8

Now find the area of the square.

2x * 2x = 4x^2

Now, subtract the areas.

31x^2 + 53x - 8

A worker carries jugs of liquid soap from a production line to a packing area, carrying 4 jugs per trip. If the jugs are packed

Allisa [31]

Answer:

B. 2

Step-by-step explanation:

We have been given that a worker carries jugs of liquid soap from a production line to a packing area, carrying 4 jugs per trip.

Since worker has made 17 trips, so total number of hugs of liquid soap would be 17 times number of jugs carried per trip.

$17\times 4=68$ .

Since each carton holds 7 jugs, so number of cartoons would be $\frac{68}{7}$ .

$\frac{68}{7}\Rightarrow \frac{63+5}{7}=9\frac{5}{7}$

We can see that there are 9 completely filled cartoons and there are 5 jugs remaining, so we need $7-5=2$ jugs.

Therefore, we need 2 jugs to fill the 10th cartoon and option B is the correct choice.

Your next math test is worth 111 points and contains 32 problems. Each problem is worth either 4 points or 3 points. How many 3

Dafna11 [192]

We call x the 4 points-worth problems and y the 3 points-worth problems

You know that x+y = 32

4x+3y = 111

You know that the difference from the x and y is 32 so write:

x = 32-y

Substitute at x the value of 32-y

4(32-y)+3y = 111

128-4y +3y = 111

-4y+3y = 111-128

-y = -17

y = 17
