Could someone please tell me the answer

Mathematics
1 answer:
Anna007 [38]3 years ago
4 0

Answer: 12.0

Step-by-step explanation: We need to find the length of one of the leg piece, so this is how we will set up our equation (x is the missing side length):

1. x^{2} + 5^{2} = 13^{2} (Simplify the square roots)

2. x^{2} +25 = 169 (Subtract 25 from 169)

3. x^{2} = 144 (Take the square root of both sides)

4. x = 12 or 12.0.

Help on the second graph?
patriot [66]

Answer:

The 2nd Graph is a function.

Step-by-step explanation:

You can tell it's a function because if you flatten the individual line segments along the x-axes, they all connect to form one long line.

HOWEVER, if some of the dots at the end of each line segment were empty circles instead, then it would not be considered a function. You can think of these as holes, not allowing the line to connect in those or that area.

Did that help? ;-;

The sides of a rectangle have length x+ 2 and width x -5. Which equation describes the area, A, of the rectangle in terms of x?​
Yakvenalex [24]

Answer:

The area in factored form is A=(x+2)(x-5).

The area in standard form is A=x^2-3x-10.

Step-by-step explanation:

The area of a rectangle is length times width.

So the area here is (x+2)(x-5).

They are probably not looking for A=(x+2)(x-5) because it requires too little work.

They probably want A in standard form instead of factored form.

Let's use foil:

First x(x)=x^2

Outer: x(-5)=-5x

Inner: 2(x)=2x

Last: 2(-5)=-10

---------------------Adding together:  x^2-3x-10.

The area in factored form is A=(x+2)(x-5).

The area in standard form is A=x^2-3x-10.

What is the probability of drawing an even numbered card, keeping it, and then drawing another even numbered card from a stack o
Oksanka [162]

Answer: 1/4

Step-by-step explanation:

In a stack of 24, the 2 mediums are odd and even cards in this question. This means that 1/2 the cards are even and 1/2 are odd. To get a even card once is a 1/2 chance, then to get it again is 1/2 x 1/2 chance or 1/4 chance. This is what I think.
