HELP DUE IN 10 MINS! Find the missing side measurement. Your answer should be a simplified radical or a whole number. (no decimals allowed)

x=

x = 3√7

Step-by-step explanation:

The Pythagorean theorem states that in a right triangle, the sum of the legs squared and added together is equal to the hypotenuse (the longest side and the one across the 90° angle)

If the legs are a and b, respectfully, and the hypotenuse is c, the equation would be:

a² + b² = c²

Let's apply this to the problem given.

9² + x² = 12²

Simplify.

81 + x² = 144

Subtract 81 from both sides.

x² = 63

Take the square root.

√(x²) = √63 = √(9 * 7) = √(3² * 7)

x = 3√7

Check the answer.

9² + (3√7)² = 12²

81 + 63 = 144

144 = 144

Thus, the answer is correct.

I hope this helps! Feel free to ask any questions! :)

i am currently in the exact same situation rn. algebra2/adv algebra is killing

step-by-step explanation:

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
