Good evening ,

______

Answer:

(4c-d+0.2)² - 10c = 33

___________________

Step-by-step explanation:

(4c-d+0.2)^2-10c

c=3.1, d=4.6​

(4(3.1) - 4.6 + 0.2)² - 10(3.1) = (12.4 - 4.6 + 0.2)² - 31 = (7.8 + 0.2)² -31 = 8² - 31 = 64-31 =33.

Answer: The value of the above expression is 18.

Step-by-step explanation:

Since we have given that

(4c-d+0.2)^2-10c

Here, c = 3.1

d = 4.6

Put the value in the above expression:

(4\times 3.1-4.6+0.2)^2-10\times 4.6\\\\=(12.4-4.6+0.2)^2-46\\\\=8^2-46\\\\=64-46\\\\=18

Hence, the value of the above expression is 18.
