Answer:

5

Step-by-step explanation:

by pythagoras theorem

(hyp)^2=(leg1)^2+(leg2)^2

the hypotenuse is the side opposite to 90 degree (BC=13)

AC=leg 1 = 12

13^2=12^2 + leg 2^2

169=144+ leg 2^2

leg2 ^2=169-144

leg2^2= 25

leg2= root 25

leg2=5

Answer:

5

Step-by-step explanation:

The first thing to think about when doing a problem is to look in the angles. BAC is a right angle, but that does not help. The next thing to notice is BA looks roughly about 1/2 the size of AC. That answer makes the most sense so the answer is 5.

soldi70 [24.7K]

Answer:

La temperatura en estos momentos es -2 grados centígrados.

Step-by-step explanation:

Dado que conoces que había una temperatura de 8°C y que a las 22 horas esta ha bajado unos 10 grados, tienes que restar estos 10 grados de la temperatura inicial para saber cuál es la temperatura actual:

8-10=-2

De acuerdo a esto, la respuesta es que la temperatura en estos momentos es -2 grados centígrados.

Pleaaseeee help me :/
Sav [38]
Hello,

\sqrt{x} - \sqrt{y} = (\sqrt[4]{x}+ \sqrt[4]{y} )( \sqrt[4]{x} - \sqrt[4]{y} )=72\\\\
\sqrt[4]{x}- \sqrt[4]{y}=6\\\\
(\sqrt[4]{x}+ \sqrt[4]{y})*6=72\\\\
\sqrt[4]{x}+ \sqrt[4]{y}=12 \\ 
\sqrt[4]{x}- \sqrt[4]{y}=6 \\\\
2 \sqrt[4]{x}=18==\textgreater\sqrt[4]{x}=9==\textgreater\ x=6561\\
2 \sqrt[4]{y}=6==\textgreater\sqrt[4]{y}=3==\textgreater\ y=81\\



Proof:
\sqrt[4]{6561} - \sqrt[4]{81} =9-3=6\\\\
 \sqrt{6561} - \sqrt{81} =81-9=72

Combine like terms <br> 4x+3(2x+5b)-4b-2x+6
Ahat [919]

Answer:

  • \boxed{\sf{8x+11b+6}}

Step-by-step explanation:

To solve this problem, you have to combine like terms of x and b from one side of the equation.

<h3>4x+3(2x+5b)-4b-2x+6</h3>

<u>Combine like terms.</u>

3(2x+5b)+4x-2x-4b+6

<u>Solve.</u>

4x-2x=2x

Rewrite the problem down.

3(2x+5b)+2x-4b+6

Expand the form.

Use a distributive property.

<u>Distributive property:</u>

A(B+C)=AB+AC

3(2x+5b)

<u>Multiply.</u>

3*2x=6x

3*5b=15b

<u>Rewrite the problem.</u>

6x+15b

6x+15b+2x-4b+6

<u>Combine like terms.</u>

6x+2x+15b-4b+6

<u>Add the numbers from left to right.</u>

6x+2x=8x

8x+15b-4b+6

<u>Then, you add again.</u>

15b-4b=11b

<u>= 8x+11b+6</u>

  • <u>Therefore, the final answer is 8x+11b+6.</u>

I hope this helps you! Let me know if my answer is wrong or not.
