Question

a2 - bc + 4a divided by c.
a = 6
b = 3
c = 8

Answer 1

To evaluate the expression (a^2 - bc + 4a) / c, we substitute the given values for a, b, and c.

First, calculate a^2:
a^2 = 6^2 = 36

Now, calculate 4a:
4a = 4 * 6 = 24

Next, calculate bc:
bc = 3 * 8 = 24

Now, substitute these values into the expression and evaluate:
(36 - 24 + 24) / 8

Simplify the numerator:
36 - 24 + 24 = 36

Now, divide the numerator by c:
36 / 8 = 4.5

Therefore, when a = 6, b = 3, and c = 8, the value of (a^2 - bc + 4a) / c is 4.5.

Answer 2

Give me an exact answer please

Answer 3

Certainly! To find the exact answer, we will substitute a = 6, b = 3, and c = 8 into the expression (a^2 - bc + 4a) / c.

First, calculate a^2:
a^2 = 6^2 = 36

Next, calculate bc:
bc = 3 * 8 = 24

Now, substitute these values into the expression and evaluate:
(36 - 24 + 4a) / c

Substituting a = 6:
(36 - 24 + 4(6)) / 8

Simplify the numerator:
36 - 24 + 4(6) = 36 - 24 + 24 = 36

Now, divide the numerator by c:
36 / 8

The exact answer is 36/8, which cannot be simplified further.
