Answer:
Step-by-step explanation:
Pythagorean theorem,
hypotenuse²= base² + altitude²
base² = hypotenuse² - altitude²
x² = 14² - 9²
= 196 - 81
= 115
x = √115
x = 10.72
1st add 7 to both sides : 3z = 21, 2nd divide both sides with 3: z = 7
Answer:
0
Step-by-step explanation:
when they have the same variable you can add them together. When adding 10x and --10x, the cancel out (negate) and you are left with 0
