2^5 + (4 + 3 + 1) = 40
((5 x 3) + (4 + 1)) x 2 = 40
9 + 8 + 3x
you can only add like terms
9 and 8 are like terms so you can add those
but 3x does not have any like terms
so the answer is
17 + 3x
Answer: 15 minutes
Step-by-step explanation:
$21 I believe (it's 1 am where I am so I'm not 100% sure but I think it's correct)
Answer:
The square root function
sqrt(144) or √144 produces a single positive value, 12.
However if you have an equation
x² = 144, then you have two possible values for x, 12 and -12.
Two ways to look at it.
x² - 144 = 0
Difference of two squares
(x+12)(x-12) = 0
x = -12, 12
x² = 144
x = ±√144
x = ±12
x = -12, 12
