A bedroom is in the shape of a square. The length of the room is 6p7q. What is the area of the bedroom in terms of p and q?

Answers

Answer:

(6p7q)²

Step-by-step explanation:

you have to square the length to find the area of a square

The area of the bedroom would be (6p7q)² square units.

What is the area of the rectangle?

The area of a rectangle is defined as the product of the length and width.

The area of a rectangle = L × W

Where W is the width of the rectangle and L is the length of the rectangle

A bedroom is in the shape of a square. The length of the room is 6p7q.

According to the given question, we can write the dimension as:

The width of the room = 6p7q units

The length of the room = 6p7q units

The area of the room = width of the room ×  length of the room

The area of the room = 6p7q × 6p7q

Apply the multiplication operation,

The area of the room = (6p7q)² square units

Therefore, the area of the room is (6p7q)² square units.

O A. y = 5x
OB. y = 5x + 10
O C. y = x
OD. y = 5x - 1

Answers

Answer:

y =5x

Step-by-step explanation:

[tex]y_{1}-y_{2} = m(x_{1} - x_{2} )[/tex]

(5 - 0) = m(1 - 0)

5 = m(1)

5 = m

[tex]y_{1}-y_{2} = m(x_{1} - x_{2} )[/tex]

y - 5 = 5(x - 1)

y - 5 = 5x - 5

y = 5x -5 + 5

y = 5x

Answers

Answer:

D

Step-by-step explanation:

I know this is super late and you probably don't need this, but for anyone who needs it, here is the answer!
Answer:

D and C

Step-by-step explanation:

We are doing the elimination method. We are subtracting so we can eliminate the x variable
 x + y = 8
- (x - y = 2)
---------------------
0x + 2y = 6
(0x is there just to show that x is eliminated but the equation is now just 2y = 6)
now solve for y (divide 2 on both sides)
y = 3

Now we can use Y to find x. Use any equation (either x + y = 8 or x - y = 2) and then plug in the y value.

x - 3 = 2.

Add 3 on both sides and you get
x = 5

Now! From the question we see that x is canoe speed and y is water current speed. And since x is 5 and y is 3, the answer is D and C since the water current is 3 and canoe speed is 5. Hope this helps!!

If a crate of 250 apples costs $95, what is the unit cost

Answers

The unit cost of an apple in a crate of 250 apples is $2.63.

Given the following data:

Total number of apples in a crate = 250 applesCost of a crate of apple = $95

To determine the unit cost of an apple:

In this exercise, you're required to calculate the cost of one apple in a crate, knowing that there are 250 apples in total at a cost of $95.

Thus, we would divide the total number of apples by the total cost of all the apples as follows:

[tex]Unit\;cost = \frac{Total\;apples}{Total\;cost}[/tex]

Substituting the given parameters into the formula, we have;

[tex]Unit\;cost = \frac{250}{95}[/tex]

Unit cost = $2.63

y = 2x + 2

Step-by-step explanation:

for each rise of 4 in y

there is a run of 2 in x

m = 4/2

m = 2

when x = 0, y = 2

therefor the y-intercept, b = 2

y = mx + b
