Answer:
Step-by-step explanation:
To find the value of x, using Pythagorean theorem.
7) x² = 12² + 12²
= 144 + 144
= 288
x = √2*12*12
x = 12√2
8) x² + 9² = 18²
x² + 81 = 324
x² = 324 - 81
x² = 243
x = √3*9*9
x = 9√3

Answer:

Step-by-step explanation:
1) Rewrite x² - 9 in the form a² - b² where, a = x and b = 3.

2) use difference of squares: a² - b² = ( a + b ) (a - b).

3) Factor out the common term x.

4) Cancle out x - 3 .

5) Simplify.
