<em>First evaluate the operations inside of the brackets</em>
-8 + 2[5 + (-4 + 1)2] <em>evaluate (-4 +1) because it is surrounded by parenthesis</em>
-8 + 2[2 + (-3)2]) <em>multiply (-3)2
</em>-8 + 2[2 - 6] <em>subtract 2 - 6 because it is surrounded by the brackets (parenthesis)
</em>-8 + 2(-4) <em>multiply 2(-4)</em>
<em>-8 - 8
-16</em>
Answer:
y = 24
angle V = 67
as a 4 sided shape, the angles all have to add up to 360 degrees.
we already have the answers for R, 120, and B, 53. We have 187 degrees left to work with.
Based of the information the tics on the sides of the figure gives us, we know that angle P and R are the same! First (just for fun, this isn't needed) we'll find X.
(x+95) = 120
-95 -95
x = 25
We know 3/4 angles now, so by subtracting their sum from 360, we'll find angle V!
360 - 53 -120 - 120 = 67
Angle V is 67
Now to find y!
(2y+19)=67
-19 -19
2y = 48
/2 /2
y = 24
For the first digit, you have two possible choices: 1 or 2. For *each* of those choices, you can choose 1 or 2 for the second digit in the number, and for each of *those*, you can choose 1 or 2 for the third digit of the number.
That’s 2 * 2 * 2 or 8 possible 3-digit numbers you can make with the digits 1 and 2.
