Solve the following equation and check your answers (1) 4x+4=3x+8
(2) 11y-2=10y+4
(3) 7-3m=5-2m
​

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

im guessing (23,14). hope this : )
