Step-by-step explanation:

$\frac{2x + 6}{5x - 20} = \frac{2x + 6}{4x + 2} \\\\ 5x - 20 = 4x + 2 \\\ 5x - 4x = 2 + 20 \\\ x = 22$

I hope I helped you.

Help pls I need answers ASAP

pishuonlain [190]

$\tt Step-by-step~explanation:$

To be able to solve this question, we need to know about the Pythagorean theorem: a² + b² = c². A and b represents the two sides that make the right angle, and C represents the hypotenuse, or the longest side, of the triangle.

$\tt Step~1:$

We know that the hypotenuse is the longest side of the triangle, so that means 9 is c. One side of the triangle is 6, and we have to solve for b. That means 6 is a. We can plug in our values to the formula like this:

$\tt a^2+b^2=c^2\\6^2+b+2=9^2\\36+b^2=81$

$\tt Step~2:$

Now that we have our equation down, we know what we have to do next: subtract 81 from 36 to get b².

$\tt 81-36=\sqrt{45}$

$\Large\boxed{\tt Our~final~answer:~b=\sqrt{45} ~(simplified:3\sqrt{5}) }$

If you roll a fair six-sided die and a fair four-sided die, what is the probability that the dice add to 7?

sveticcg [70]

1/6.

For any given roll on a four-sided die, there is exactly one roll on a six-sided die (1/6 chance) which will sum to 7.

Since it doesn’t matter what you roll on the four-sided die, the chance is always 1/6 with a fair six-sided die.

One interesting result of this is that only the 6-sided die has the be fair for this result to hold. The 4-sided die can be very biased in any direction and the final result will still be 1/6.
