Answer:

63mm

Step-by-step explanation:

7mm+8mm=15.

15×15=225

12×12=144(area equals base times height) add 225-144=81(here we are using the Pythagoras theory) so you search for the square root of 81 which is 9 meaning the height is 9. since we say area is 1/2base times height we should take 1/2 ×9×12=63.if the answer doesn't match with the answer in your book please tell me right away so that I can try another method thank you

A company is setting up offices in two different cities. The number of employees hired by the company for its office in city A o
labwork [276]
For this case we have the following functions:
 City A:
 f (x) = 9x
 City B:
 g (x) = 3 (2) ^ x
 The total number of employees will be:
 h (x) = f (x) + g (x)
 Substituting we have:
 h (x) = 9x + 3 (2) ^ x
 Rewriting we have:
 h (x) = 3 (3x + (2) ^ x)
 For 5 months we have:
 h (5) = 3 * (3 * (5) + (2) ^ 5)
 h (5) = 141
 Answer:
 the total number of employees in the company over x months and the total number of employees will be 141 when the function is:
 h (x) = 3 (3x + (2)^x); 5 months
