Answer:  4*sqrt(66)

This is the same as saying 4\sqrt{66}

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

Explanation:

x = length of segment BD

Because BD is an altitude of triangle ABC, this means the triangle is split into two smaller right triangles which are similar to the original. All three right triangles are similar to one another.

What this leads to is the proportion

CD/BD = BD/AD

Apply substitution and solve for x.

24/x = x/44

24*44 = x*x .... cross multiply

1056 = x^2

x = sqrt(1056)

x = sqrt(16*66)

x = sqrt(16)*sqrt(66)

x = 4*sqrt(66)

Notice how I factored 1056 in such a way that I pulled out the largest perfect square factor (16). Then I used the rule \sqrt{x*y} = \sqrt{x}*\sqrt{y}
 to break up the root.

Can someone help with this I didn’t pay attention in math and I have homework ‍♀️
Lady bird [3.3K]

Answer:

C.

Step-by-step explanation:

Even though it is absolute value, 17 is still the greatest answer. If a number is in absolute value it will never be negative, only positive values can come out of an absolute value.

An example for absolute value would be if you had to measure the amount of distance away from something, even if its behind you, it would still be a positive number of length away from you.

If you had the absolute value of -25, it would automatically be equal to 25.

So circling back to the original problem, the absolute value of 17 would be greater than 3, -4 and -8. If (hypothetically) it was the absolute value of -17 it would still be greater because it would equal 17.

I hope that made sense, im sorry that it's a bit lengthy. Have a good day :)

Quadrilateral ABCD with vertices A(4, 3), B(4, -2), C(-4, -2) and D(-4, 3) is a rectangle, find the length of the diagonals.
marin [14]
Distance between two points P(x1,y1), Q(x2,y2):
D=sqrt((x2-x1)^2+(y2-y1)^2)

Polygons are generally named in order along the perimeter, so that for a rectangle ABCD, AC or BD are diagonals.
Here, we need the distance between points A(4,3) and C(-4,-2)
Applying the above formula for distance between two points, 

D=sqrt((4-(-4))^2+(3-(-2))^2)=sqrt(8^2+5^2)=sqrt(64+25)=sqrt(89)
