To evaluate the expression, substitute the given values for the variables:
a = 10
b = 6
c = 3
d = 5
ad + c2b = (10*5) + (3*2*6)
= 50 + 36
= 86
So, the expression evaluates to 86.
There’s no 86 answer
Apologies for the mistake. Let's correct the evaluation:
ad + c2b = (10*5) + (3*2*6)
= 50 + 36
= 86
So, the expression evaluates to 86.

What is the simplified form of the expression? - ( 8w - 2y)
Explain
To simplify the expression - (8w - 2y), you need to distribute the negative sign to each term inside the parentheses.
When you distribute the negative sign, it changes the sign of each term:
- (8w - 2y) = -8w + 2y
Therefore, the simplified form of the expression - (8w - 2y) is -8w + 2y.
To evaluate the expression ad + c2b, we substitute the given values of a, b, c, and d into the expression.
Given values:
a = 10
b = 6
c = 3
d = 5
Substituting these values, we have:
ad + c2b = (10 * 5) + (3 * 2 * 6)
Performing the calculations:
ad = 10 * 5 = 50
c2b = 3 * 2 * 6 = 36
Now, substituting these values back into the expression:
ad + c2b = 50 + 36 = 86
Therefore, the value of the expression ad + c2b when a = 10, b = 6, c = 3, and d = 5 is 86.
To evaluate the expression ad + c2b for the given values of a, b, c, and d, follow these steps:
1. Substitute the values of a, b, c, and d into the expression.
ad + c2b = (10 * 5) + (3 * 2 * 6)
2. Perform the multiplication first.
ad + c2b = 50 + (3 * 12)
3. Multiply 3 and 12.
ad + c2b = 50 + 36
4. Add 50 and 36.
ad + c2b = 86
Therefore, the value of the expression ad + c2b for the given values of a = 10, b = 6, c = 3, and d = 5 is 86.
