QUESTION POSTED AT 18/01/2020 - 07:38 AM

As this is a unitless problem, let us try to deal with it as if it does have units. Since we are already given the length and width of a rectangle, we can solve for the area by multiplying. After getting the area, we divide this by the area a wheelbarrow can cover to obtain the expression for how many wheelbarrows we need.

Rectangle length = 10x^2 + 90x

Rectangle width = 5x^2

Rectangle area = length * width = 5x^2(10x^2 + 90x)

Rectangle area = 50x^4 + 450x^2

Dividing:

_5x^2_+_45____10x^2|50x^4 + 450x^2 50x^4 -------- 450x^2 450x^2 --------- 0

Therefore, the expression for how many wheelbarrows are to be used is 5x^2 + 45 wheelbarrows.

Rectangle length = 10x^2 + 90x

Rectangle width = 5x^2

Rectangle area = length * width = 5x^2(10x^2 + 90x)

Rectangle area = 50x^4 + 450x^2

Dividing:

_5x^2_+_45____10x^2|50x^4 + 450x^2 50x^4 -------- 450x^2 450x^2 --------- 0

Therefore, the expression for how many wheelbarrows are to be used is 5x^2 + 45 wheelbarrows.

The *correct answers* are:

B=(xy + x)(xy + x) ; C=(2x – 3)(–3 + 2x) ; and E=(4y² + 25)(25 + 4y²)

**Explanation**:

In order to have a perfect square trinomial, we must multiply two binomials that are exactly the same. For (xy+x)(xy+x), are multiplying two identical binomials.

For (2x-3)(-3+2x), we are multiplying two binomials that are the same but written in a different order. The same is true of (4y² + 25)(25 + 4y²).

To graph this we find the x- and y-intercepts. The x-intercept would be at 8 and the y-intercept would be at 6.

**Explanation**:

The equation is 6x+8y=48. An x-intercept is the point where the data crosses the x-axis. All points on this line will have a y-coordinate of 0, so we replace y with 0 and solve:

6x+8(0)=48

6x=48.

Divide both sides by 6:

6x/6=48/6

x=8.

We go to 8 on the x-axis and plot the point.

A y-intercept is the point where the data crosses the y-axis. All points on this line will have an x-coordinate of 9, so we replace x with 0 and solve: 6(0)+8y=48

0+8y=48

8y=48.

Divide both sides by 8:

8y/8 = 48/8

y=6.

We go up to 6 on the y-axis and plot the point. We then draw a line through these two points.

QUESTION POSTED AT 18/01/2020 - 06:36 AM

**Answer: **Hello mate!

we have the system of equations

30x + 30y = 450

20x + 25y = 345

where x is the number of square feet of snow that Melinda shovels in one minute, and y is the number of square feet of snow that Paul shovels in one minute.

Let's solve the system of equations, first, isolate one of the therms in the first equation, for example, x.

30x+30y = 450

x + y = 450/30 = 15

x = 15 - y

now we can replace it in the second equation and solve it for y.

20x + 25y = 345

20(15 - y) + 25y = 345

300 - 20y + 25y = 345

5y = 45

y = 45/5 = 9

Paul can shovel 9 square feets of snow in one minute, now replace it in the first equation and solve it for x.

x + y = 450/30 = 15

x + 9 = 15

x = 15 - 9 = 6

so melinda sholves 6 square feet of snow in one minute.

The question is:

How much more can Paul shovel in 1 minute than Melinda?

We need to see the difference y - x = 9 - 6 = 3

this means that paul shovels 3 more square feet per minute than Melinda.
