Answer:

I believe is A.

Step-by-step explanation:

you will have x^2 (which is the big square) + 1x (which is the lower line) + 3x (which are the 3 line verticals) + 3 (which are the 3 squares)

Answer: Choice A

Across the top we have x+3 since the square has side length x and the long rectangles have their short side equal to 1. Three of those rectangles combined like that make 1+1+1 = 3

Across the far left side, we have a vertical distance of x combined with just 1 this time (instead of 3) leading to x+1

Which set represents a pythagorean triple (1 point)?

Vinil7 [7]

A pythagorean triple is A squared + B squared = C squared. A and B being the smaller numbers (side lengths) whilst C is the larger number (diagonal). Any two numbers (sides) that added together after each being squared equals the bigger number (diagonal) squared is a pythagorean triple.

The perimeter of a rectangle is 84cm.

Tatiana [17]

Answer:

39 cm

Step-by-step explanation:

The perimeter of a rectangle is given as 2 (w + l) or 2w + 2l, where w and l are the sides.

Let us use <em>w</em> as 3 cm.

The perimeter of the rectangle is 2(3) + 2l = 6 + 2l

6 + 2l = 84 cm

We move the 6 to the left hand side and it goes from positive to negative.

2l = 84 - 6cm

2l = 78 cm

Divide both sides by 2.

l = 39 cm

There you have the answer for side <em>l</em>.

Hope this helps.

Problem PageQuestion It takes an older pump twice as long to drain a certain pool as it does a newer pump. Working together, it

umka2103 [35]

Answer:

It will take 6 hours for the new pump to drain the pool.

Step-by-step explanation:

As the complete question is not given, the complete question is found online and is attached herewith

Let the rate of new pump is given as x=W/t_1

Let the rate of the old pump is given as y=W/t_2

it is given that the time t_2=2t_1

So by substituting the values of t_2 in the rate equation of y

y=W/2t_1

y=(W/t_1*2)=x/2

Also the total rate of both the pumps is given as W/t3 where t3 is given as 4 hours so the equation becomes

x+y=W/4

x+x/2=W/4

3x/2=W/4

As x=W/t_1

3W/2t_1=W/4

Now as W is same on both sides so

3/2t_1=1/4

12=2t_1

t_1=6 hours

So it will take 6 hours for the new pump to drain the pool.
