Find the missing side of the right triangle. Side a = 10 and side b = 5
Levart [38]

Assuming that C is the hypotenuse...

The formula you want to use is:

a^2 + b^2 = c^2

We start by squaring 10, which is 100. 5^2 is 25. Now that we have the values, we can do the equation.

100+25=c^2                  100+25=\sqrt{125}

Now, square root \sqrt{125}

C= 11.180

seropon [69]
<h3>Answer: 5/51</h3>

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

Explanation:

We have 6 green out of 6+6+6 = 18 total

The probability of getting green is 6/18 = 1/3.

After selecting that green jelly bean and not putting it back, we have 6-1 = 5 green out of 18-1 = 17 total.

The probability of selecting another green is 5/17.

Multiply the two fractions 1/3 and 5/17

(1/3)*(5/17) = (1*5)/(3*17) = 5/51

The probability of selecting two greens in a row is 5/51 where we do not put the first selection back. We also do not replace the green jelly bean with some other identical copy.

Note: 5/51 = 0.098039 approximately

What is the product of (7x+3)^2
Natali [406]

Answer:

49x² + 42x + 9

Step-by-step explanation:

Given

(7x + 3)²

= (7x + 3)(7x + 3)

Each term in the second factor is multiplied by each term in the first factor, that is

7x(7x + 3) + 3(7x + 3) ← distribute both parenthesis

= 49x² + 21x + 21x + 9 ← collect like terms

= 49x² + 42x + 9
