34
19
38
98
To evaluate the expression, substitute the given values for h, k, and e into the expression:
2(k^3+h-e) = 2(2^3+18-7)
= 2(8+18-7)
= 2(26-7)
= 2(19)
= 38
Therefore, the value of the expression 2(k^3+h-e) when h=18, k=2, and e=7 is 38.
To evaluate the expression 2(k^3+h-e) when h=18, k=2, and e=7, we substitute the given values into the expression.
2(k^3+h-e) = 2(2^3+18-7)
First, we evaluate inside the parentheses:
2(2^3+18-7) = 2(8+18-7)
Next, we simplify inside the parentheses:
2(8+18-7) = 2(26-7)
Now, we simplify the multiplication:
2(26-7) = 2(19)
Finally, we calculate the final result:
2(19) = 38
Therefore, the value of the expression 2(k^3+h-e) when h=18, k=2, and e=7 is 38.
To evaluate the expression 2(k^3 + h - e) when h = 18, k = 2, and e = 7, we substitute the given values into the expression and perform the necessary calculations.
Step 1: Substitute the values of h, k, and e into the expression:
2(2^3 + 18 - 7)
Step 2: Simplify the expression within the parentheses:
2(8 + 18 - 7)
Step 3: Perform the addition and subtraction within the parentheses:
2(26 - 7)
Step 4: Perform the subtraction inside the parentheses:
2(19)
Step 5: Perform the multiplication:
38
Therefore, the value of the expression 2(k^3 + h - e) when h = 18, k = 2, and e = 7 is 38.
