First you add the 1/4 and 3/4 together forgetting the /4 and adding the 1+3, that makes 4/4 which is a 1 then add that 1 to the 1 and 2 left over to get the answer
Answer:
5
Step-by-step explanation:
3(2x-5)-2=x+8
6x-15-2=x+8
6x-17=x+8
6x-x-17=8
5x-17=8
5x=8+17
5x=25
x=25/5
x=5
Pythagorean theorem: a² + b² = c²
a² and b² are the legs, and c² is the hypotenuse.
Plug in 9 to a² and b² since you know that both the right triangle's legs are 9 cm.
9² + 9² = c²
81 + 81 = c²
162 = c²
Square root both sides.
c = 12.7 cm
Answer:
20 feet.
Step-by-step explanation:
Pythagoreans theorem states that a^2 + b^2 = c^2
a = 12, squared = 144
b = 16, squared = 256
144 + 256 = 400
√400 = 20
20 feet is the answer.
Hope this helps.
