Answer:

54.25

Step-by-step explanation:

hi! so length x width = the area so your going to want to put in the numbers

8.75 x 6.2 = 54.25

54.25 is the area, love.

if there is the depth then you would multiply 54.25 by the depth. alright?

if you need anything else let me know.

Answer:

  =54.25 m^2

Step-by-step explanation:

We will assume the pool is a rectangle

A = l*w

A = (8.75) * (6.2)

  =54.25 m^2

Point slope formula.. help
sertanlavr [38]
<h3>Answer:   y = 2x+6</h3>

========================================================

Explanation:

We'll need the slope first

m = slope

m = (y2-y1)/(x2-x1)

m = (0-(-4))/(-3-(-5))

m = (0+4)/(-3+5)

m = 4/2

m = 2

The slope is 2.

Next, pick either of the two given points to play the role of (x_1,y_1)

Let's say we picked on (-5,-4). The order doesn't matter so you could easily pick the other point as well.

We'll plug these items into the point slope equation below to solve for y.

y - y_1 = m(x - x_1)\\\\y - (-4) = 2(x - (-5))\\\\y  + 4 = 2(x +5)\\\\y  + 4 = 2x +10\\\\y  = 2x +10-4\\\\y  = 2x +6\\\\

Or we could have picked on (-3,0). The m value stays the same (at m = 2)

y - y_1 = m(x - x_1)\\\\y - 0 = 2(x - (-3))\\\\y = 2(x +3)\\\\y = 2x+6\\\\

This one takes a few less steps. Either way, we get to the same answer.

You only need to pick one of the points, but doing both of them helps show that the two points are on the same line. It helps confirm the answer.

-----------------------

Another way to check the answer is to plug the (x,y) coordinates into y = 2x+6 for each point.

So let's say we check (x,y) = (-5,-4)

y = 2x+6

-4 = 2(-5)+6 ... replace x with -5, replace y with -4

-4 = -10+6

-4 = -4

This confirms the first point. I'll let you check the second point.

Use the following diagram and information to answer the question.
Reika [66]

Answer:

  b)  Julie can use properties of congruent triangles to show that AB≅BC and BC≅CD. Then she can show BC≅AD because opposite sides of a parallelogram are congruent

Step-by-step explanation:

On the assumption that Julie must show all four sides to be congruent, the one remaining step after using the properties of congruent triangles is to show that side AD is congruent to the rest of the sides. Answer choice B describes that.

___

IMO, Julie is finished after she shows∠A≅∠B and AB≅BC, because a parallelogram will be a square if adjacent sides are congruent (makes it a rhombus) and adjacent angles are congruent (makes it a rectangle). A rhombus that is a rectangle is a square.
