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.

The slope would have to be -3
7b is just 7 x b and if b is 6 its just 7 x 6
which the answer is 42
The area of a rectangle is easy to compute.
Area = length times height
Area = 8 cm * 4 cm = 32 square centimeters
