Answer:

#1

Step-by-step explanation:

The associative property of addition states that we can "flip" two expressions that are being added. Therefore, our answer is the first one because it can be rewritten as 3x + (-7y) which then is equivalent to -7y + 3x.

The answer is one if you try plugging x in as a number and y as one for an example (1,0) where x is 1 and y is 0

You must calculate the number of sheets of plywood needed for subflooring. Each sheet of plywood measures 4'by 8. The measuremen
snow_lady [41]

Answer:

25 sheets of plywood will be needed

Step-by-step explanation:

Each sheet of plywood measures 4ft*8ft=32ft^{2}.

We have to cover the surface of the house, minus the surface of the hole of the stairs.

Surface _{to cover} = Surface _{house} -Surface _{hole}= (28ft*30ft)-(12ft*4ft)= 840ft^{2}-48ft^{2}=792ft^{2}

To know how many sheets will be needed, we divide the surface to be covered by the surface of each sheet

Sheets_{needed} =\frac{Surface _{house}}{Surface _{sheet}} =\frac{792ft^{2}}{32\frac{ft^{2}}{sheet} } = 24,75 sheets

As we can't buy 0,75 of a sheet, we round it up, i.e. we will need 25 sheets of plywood for subflooring.

Dylan has a square piece of metal that measures 10 inches on each side. he cuts the metal along the diagonal, forming two right
Artemon [7]
You need to use the Pythagorean theory. a² + b² = c². So you would end up with 10²+10²=c². So, 10²=100, therefore you would end up with 200=c². In order to find the length of the hypotenuse, you need to find C. To do this, you need to undo the square and find the square root of 200 and C. So, you would get √200=√c² which would equal 14.1 inches. Then, if needed to check the answer, plug the 10,10,and 14.1 back into the a²+b²=c² and it should make the statement true.

Answer:

a=35, b=14, c=5

Step-by-step explanation:

b+6=20, b+6-6=20-6, b=14

4c-6=14, 4c-6+6=14+6, 4c=20, 4c/4=20/4, c=5

a triangle's angles always add up to 180, 180-55-90(the square means right angle)=35
