Answer:

No, it does not follow the Pythagorean Theorem.

Step-by-step explanation:

A right triangle must follow the equation a^2 + b^2 = c^2 for its sides to be true. 20^2 + 40^2 = 2000.

the square root of 2000 equals about 44.7213595.

Thus, a triangle with sides 20, 40, and 80 is not a right triangle.

Answer: no

because using Pytago theorem, we have:

20² + 40² ≠ 80²

80² + 20² ≠ 40²

80² + 40 ² ≠ 20²

Step-by-step explanation:

n200080 [17]

Answer:

part A: expression 1: 6(8m+2)

          expression 2: 6m+12+42m

Part B: 6(m+2+7m)= 6(8m+2)

combine like terms is 6(m+2+7m), so it is 6(2+8m) or 6(8m+2)

6(8m+2)= 6(8m+2)

Part C: 6m+12+42m=6(m+2+7m)

m=0

6(0+2+7(0))=6(0)+12+42(0)

6(2)= 12

12=12
