What is the value of 4^2 - 2(3 x 5 + 1)?
My answer~ I took (3 x 5 + 1) = 16 x 4^2 = 16 - 2 = 14, and I got 254, but that's not on my answer recommendations, I don't understand this at all, plz help meh!!

Thank you so much!!
Joaquin buys 3 packs light bulbs. Each pack contains 12 light bulbs. after changing the bulbs in his house, he has 15 bulbs left, how many light bulbs did he use?
12 x 3 = 36, 36 - 15 = 21,
my answer is 21, is this correct?
You're welcome.
Yes, 21 is correct.
Yes, that's correct.
Well, looks like you've got a math problem that's got you feeling a bit like a clownfish out of water! Don't worry, I'm here to help you swim through these numbers.
First, let's tackle the expression inside the parentheses, (3 x 5 + 1). Well, 3 x 5 is 15, and then we add 1, which gives us 16.
Now, onto the next step. We have 4^2 - 2(16). Now, 4^2 means 4 raised to the power of 2, which equals 16. So we now have 16 - 2(16).
The next step is to multiply 2 by 16, which gives us 32. So we have 16 - 32.
And finally, subtracting 32 from 16 will give us -16. So the correct answer is C, -16.
Don't worry, math can be a bit of a clown sometimes, but with a little humor and persistence, you can solve any problem!
To find the value of the expression 4^2 - 2(3 x 5 + 1), let's break it down step by step:
First, let's simplify the expression within the brackets: 3 x 5 + 1 = 15 + 1 = 16.
Now, we have the expression: 4^2 - 2(16).
Next, let's calculate the exponentiation, 4^2, which means 4 raised to the power of 2: 4^2 = 4 x 4 = 16.
Now, we can replace this in our expression: 16 - 2(16).
Next, let's calculate the multiplication within the brackets: 2(16) = 2 x 16 = 32.
Now, we can replace this in our expression: 16 - 32.
Finally, let's subtract: 16 - 32 = -16.
So, the value of the expression 4^2 - 2(3 x 5 + 1) is -16.
Thus, the correct answer is C. -16.
