Question

(6-с)^2-с(с-8) найдите его значении при с=1/2

Answer 1

Ответ: 34

Объяснение:

36-12c+c^2-c^2+8c=36-4c; при c=1/2: 36-2=34

Answer 2

To find the value of the expression (6c)^2 - c(c - 8) when c = 1/2, simply substitute the value of c into the expression and then perform the calculations:

Step 1: Substitute c = 1/2 into the expression: (6 * (1/2))^2 - (1/2)((1/2) - 8)

Step 2: Perform the calculations: (3)^2 - (1/2)((1/2) - 8) 9 - (1/2)(-15/2) 9 + 15/4 (36 + 15) / 4 51 / 4

So, the value of the expression (6c)^2 - c(c - 8) when c = 1/2 is 51/4 or 12.75.
