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
Answer:
C. 4
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
