(3y-5 + 2y)*2 = (5y-5)*2 = 10y-10
The answer is C. |-31|=3
The absolute value of -31 should’ve been 31 not 3
its step 2 he did not subtract it right hope this helps and have a great day and get some sleep lol
Answer:
it is a right triangle
Step-by-step explanation:
confirm if it is a right triangle using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
12² + 35²
144 + 1225 = 1369
square toot of 1369 is 37
so
12² + 35² = 37²
Step-by-step explanation:
If I'm understanding what a "proof" means, some answers could be:
2 + 3 = 5
4 + 15 = 19
8 + 21 = 29
Hope this helps you! Have a good night!
