Evaluate the following expression when x = 5: 8(2x+6)(1 point) Responses 86 86 24 24 104 104 128
To evaluate the expression when x = 5, we substitute x with 5 in the expression:
8(2(5) + 6)
This simplifies to:
8(10 + 6)
8(16)
And the final result is:
128
To evaluate the expression when x = 5, we substitute the value of x into the expression:
8(2x + 6)
Since x = 5:
8(2(5) + 6)
First, we simplify within the parentheses:
8(10 + 6)
Next, we simplify the addition within the parentheses:
8(16)
Finally, we multiply:
128
Therefore, the expression evaluates to 128 when x = 5.
To evaluate the expression when x = 5, we need to substitute the value of x into the expression and perform the calculations accordingly.
The given expression is: 8(2x + 6)
Substituting x = 5, we get: 8(2 * 5 + 6)
First, we need to evaluate what's inside the parentheses: 2 * 5 = 10
Next, we add the result to 6: 10 + 6 = 16
Now, we multiply 8 by the result: 8 * 16 = 128
Therefore, the value of the expression when x = 5 is 128.
Evaluate the following expression: 3x+6−y when x = 2 and y = 5(1 point) Responses 10 10 7 7 6 6 4
To evaluate the expression when x = 2 and y = 5, we substitute the values into the expression:
3x + 6 - y
Substituting x = 2 and y = 5, we get:
3(2) + 6 - 5
Multiplying:
6 + 6 - 5
Adding and subtracting:
12 - 5
7
Therefore, the value of the expression when x = 2 and y = 5 is 7.
Evaluate the following expression: 5c−2k when c = 7 and k = 3(1 point) Responses 7 7 29 29 3 3 34
To evaluate the expression when c = 7 and k = 3, we substitute the values into the expression:
5c - 2k
Substituting c = 7 and k = 3, we get:
5(7) - 2(3)
Multiplying:
35 - 6
Subtracting:
29
Therefore, the value of the expression when c = 7 and k = 3 is 29.
Evaluate the following expression: 2(k3+h−e) when h = 18, k = 2, and e = 7(1 point) Responses 34 34 19 19 38 38 98
To evaluate the expression when h = 18, k = 2, and e = 7, we substitute the values into the expression:
2(k^3 + h - e)
Substituting h = 18, k = 2, and e = 7, we get:
2(2^3 + 18 - 7)
Evaluating the exponent:
2(8 + 18 - 7)
Performing the addition and subtraction within the parentheses:
2(8 + 11)
Multiplying:
2(19)
And the final result is:
38
Therefore, the value of the expression when h = 18, k = 2, and e = 7 is 38.
