Answer:
Your answer would be 4, but correct me if I'm wrong.
Step-by-step explanation:
w(a)=3a to the power of 2+2; Find w(a-3) = 4
Hey there! :)
3 - (-2) = ??
Let's keep in mind that a negative times a negative is always a positive!
In addition, let's also remember that parenthesis mean multiplication - so that's how we know that we're multiplying!
So, since a negative times a negative equals a positive, then we know that this question is essentially just asking us what 3 + 2 is!
In case we aren't sure how to do this, let's look at our fingers! We start out with 3 fingers, and add 2 more fingers to it! So, 3 fingers to 2 fingers equals 5 fingers!
Therefore, our answer is 5.
3 -(-2) = 5

The values x and y are determined when we use the substitution method.
y = x + 5
Apply eh value of y into the equation to solve for x.
3x + y = 25
3x + x + 5 = 25
Combine like terms
3x + x = 4x
4x + 5 = 25
-5 -5 4x = 20
4x/4 = 20/4
x = 20/4
x= 5
Now we know the value of x, and we need to solve for y.
y = x + 5
y = 5 + 5
y = 10
10 = 10
Now we know both of these values.
Answer:
x = 5
<span>y = 10</span>
