If x equals -2 and y equals 5 what is the value of the expression 5y-3x?

5(5) is 25. 3(-2) is (-6). The expression becomes 25 - (-6). When subtracting a negative number, you actually "add the opposite," so the expression is now 25 + 6 (positive 6 is "the opposite" of -6); the value is 31.

what is the value when (n-2)^2+n-1when n=4?
To find the value of (n-2)^2 + n-1 when n=4, we simply substitute 4 for n in the expression: (n-2)^2 + n-1 When we do this, the expression becomes: (4-2)^2 + 4-1 Now we need to simplify the expression within the parentheses first. The expression within the parentheses is (4-2)^2, which means we need to subtract 2 from 4 and then square the result. So, we get: 2^2 Which equals 4. Now we can substitute this value back into the original expression to get: 4 + 4-1 Next, we simplify the expression 4-1, which equals 3. So, the expression becomes: 4 + 3 And we can simplify that further to get: 7 So, when n=4, the value of (n-2)^2 + n-1 is 7
