Answer:

C. 4

Step-by-step explanation:

Substitute 1 in for c, and 2 in for d

6c^2-5d+8

6(1^2)-5(2)+8

Solve the exponent first (PEMDAS)

6(1)-5(2)+8

Multiply

6-10+8

Subtract

-4+8

Add

4

Hope this helps! :)

6c² - 5d + 8

You know the values of c and d:

c = 1

d = 2        So substitute/plug it into the expression

6c² - 5d + 8       Plug in 1 into "c" since c = 1, and plug in 2 into "d" since d = 2

6(1)² - 5(2) + 8        

6 - 10 + 8

4               Your answer is C
