7×5(2)-1=
7×10-1=69
nth term= 69.
maybe.
What are the answer of your list ?
What grade is this? I got no idea
5/8÷8=5/8×1/8
5/64 is the answer
Answer:
Yes
Step-by-step explanation:
If a triangle is a right triangle, the 3 side lengths will check out in the Pythagorean Theorem.
![a^2+b^2=c^2](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2)
where a and b are the legs and c is the hypotenuse.
The legs are the 2 shorter lengths and the hypotenuse is the longest length. The 3 side lengths are: 16,63 and 65. Therefore, 16 and 63 are the legs and 65 is the hypotenuse.
a=16
b=63
c=65
![16^2+63^2=65^2](https://tex.z-dn.net/?f=16%5E2%2B63%5E2%3D65%5E2)
Evaluate each exponent.
16^2=16*16=256
![256+63^3=65^2](https://tex.z-dn.net/?f=256%2B63%5E3%3D65%5E2)
63^2=63*63=3969
![256+3969=65^2](https://tex.z-dn.net/?f=256%2B3969%3D65%5E2)
65^2=65*65=4225
![256+3969= 4225](https://tex.z-dn.net/?f=256%2B3969%3D%204225)
Add 256 and 3969
![4225=4225](https://tex.z-dn.net/?f=4225%3D4225)
The statement above is true; 4225 is equal to 4225. Therefore, this is a right triangle because the side lengths check out when plugged into the Pythagorean Theorem.
