Question

4c(c-2)-(c-4)2 при c=1/3​

Answer 1

Ответ:

=3c^2-16

Объяснение:

=4c^2-8c-(c^2-8c+16)=4c^2-8c-c^2+8c-16=3c^2-16

Answer 2

Перед тем как подставить мы упрощаем выражение:

4c(c-2)-(c-4)2=4с^2-8с-2с+8=4с^2-10с+8=

4× 1/3 ^2 -10×1/3+8=4×1/9 -10/3+8=4/9-10/3+8=46/9=5 1/9

Answer 3

To evaluate the expression 4c(c-2)-(c-4)2 when c=1/3, we can substitute 1/3 in place of every occurrence of c and then simplify the expression using the order of operations.

So, let's begin:

4c(c-2)-(c-4)2 with c=1/3

= 4(1/3)(1/3-2)-((1/3)-4)2 (Substituting c=1/3)

= 4/3 * (-5/3) - (-11/3)^2

= -20/9 - 121/9

= -141/9

= -47/3

Therefore, the value of 4c(c-2)-(c-4)2 when c=1/3 is -47/3.
