Can you be more specific about what is P(5)? The probability would probably be around five though.

Answer:

$\Huge\boxed{x=7}$

Step-by-step explanation:

Hello there!

The first thing we want to do is find the measure of the large leg

To do so we use the Pythagorean theorem which says $a^2+b^2=c^2\\$

where a and b are legs and c is the hypotenuse

we want to find b given the hypotenuse and short leg

so $b^2=c^2-a^2$

all we have to do is plug in a ( a = short leg so a would equal 12) and c ( c = hypotenuse so c would equal 37)

$b^2=37^2-12^2\\37^2=1369\\12^2=144\\1369-144=1225\\b^2=1225\\\sqrt{b^2} =b\\\sqrt{1225} =35\\b=35$

so the longer leg is equal to 35

35=5x

divide each side by 5

5x/5=x

35/5=7

we're left with x=7

Explain the different ways that you can use multiplication to estimate and solve division problem

oee [108]

if I read your question correctly, you can use multiplication to get the same answer with division. for example;

2 x 2 = 4; 4 divided by 2 = 2.

8 x 4 = 32; 32 divided by 8 = 4; 32 divided by 4 = 8.

5 x 6 = 30; 30 divided by 5 = 6; 30 divided by 6 = 5

hope this helped! :D
