Total profit is defined as total​ revenue, R(x), minus total​ cost, C(x), and is given by the function ​P(x)=​R(x)​-C(x). Given ​R(x) =58x - 0.4x^2 and ​c(x)=3x+13, find each of the following. ​b) ​R(80)

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to

pls mark as brainliest

step-by-step explanation:

one day the were 5 ducks, and their king told them to multiply their kingdom. so each went their own seperate way and met 4 other ducks on their journey.

when the ducks returned to their kingdom, it was discovered that there were 5 groups of 5 ducks. when the kind counted the number of ducks in total (including the ones he sent out earlier) he counted 25.

therefore 5 times 5 is 25.

the end. : )
