To evaluate the expression 4c+7^2-r+2w when w=3, c=5, and r=11, we substitute the given values into the expression:
4(5)+7^2-11+2(3)
= 20+49-11+6
= 69+6-11
= 75-11
= 64
Therefore, the value of the expression is 64.
To evaluate the expression 4c + 7^2 - r + 2w when w = 3, c = 5, and r = 11, substitute the given values into the expression and simplify:
4c + 7^2 - r + 2w
= 4(5) + 7^2 - 11 + 2(3)
= 20 + 49 - 11 + 6
= 69 - 11 + 6
= 58 + 6
= 64
Therefore, the value of the expression is 64.
To evaluate the given expression 4c + 7^2 - r + 2w, where w = 3, c = 5, and r = 11, we substitute the respective values and perform the operations.
1. Substitute the values:
4(5) + 7^2 - 11 + 2(3)
2. Simplify the exponent:
4(5) + 49 - 11 + 2(3)
3. Perform the multiplication and addition:
20 + 49 - 11 + 6
4. Combine like terms:
69 - 11 + 6
5. Perform subtraction and addition:
58 + 6
6. Calculate the final answer:
64
Therefore, the evaluated expression 4c + 7^2 - r + 2w, when w = 3, c = 5, and r = 11, is equal to 64.
