Parenthesis are something you can use in math problems that mean anything inside of them is what you have to solve first. In PEMDAS P is parenthesis which means that is first.
Answer:
60
Step-by-step explanation:
8640/60 is 144. 144 is a perfect square. 12*12 is 144
In order going down:
5 3/5
6 5/6
4 2/3
10 1/3
11 2/3
Answer:
x={(y+1) / 5}²
Step-by-step explanation:
y = 5√x +3 -4
⇒y = 5√x -1
add 1 on both sides
⇒ y + 1 = 5√x
divide both sides by 5
⇒(y+1) / 5 = (5√x) /5
⇒(y+1) / 5 = √x
now, square both sides
⇒{(y+1) / 5}² = (√x)²
∴{(y+1) / 5}² = x
Take second equation here,
2x + 9 = -12
2x = -12 - 9
2x = -21
Multiply by 2,
4x = -42
Now, substitute the vaue of 4x in 1st equation,
-42 - y = 2
-y = 2 + 42
y = -44
In short, Your Answer would be -44
Hope this helps!
