Step-by-step explanation:
I'm not sure about the answer
Not sure if my picture answer make sense so, when you have a^2 and b^2 to find c^2 u add then and then square root it to get c. e.g 81^2 + 108^2 = 18225 then u square root it and get 135. when u are given the hypotenuse (which is always c^2) u take that away from the a^2/b^2 and square root. e.g 8^2-4^2 which is 48 which can’t be square rooted so just leave as root48
Answer:
His mistake was he didn't multiply 3(4) when he was opening the parenthesis
Step-by-step explanation:
Correct solution:
12x – 5 = 3(x + 4)
Open parenthesis
12x – 5 = 3x + 12
Collect like terms
12x - 3x = 12 + 5
9x = 17
x = 17/9
x = 9 8/9
Incorrect solution:
12x – 5 = 3(x + 4)
His mistake was he didn't multiply 3(4) when he was opening the parenthesis
12x – 5 = 3x + 4
12x = 3x - 1
9x = -1
