Step-by-step explanation:
A-
Multiply 2.5 by 3.5 and you'll get 8.75 Multiply 3.5 by 1.2 and you'll get 4.2; divide and your answer will be 2.1 Add to 8.75 Get 10.85 Subtract from area of door ( 3m because 1.5 times 2 is 3) and you'll get 7.85

Answer:
For this we need to solve using the transposition method
Step-by-step explanation:
We need to shift variables and constants from the RHS to LHS sgregating the x. + becomes - and x becomes /
-28 < 2x - 10 < -10.....add 10 to all sections
-28 + 10 < 2x - 10 + 10 < -10 + 10....simplify
-18 < 2x < 0...divide all sections by 2
-18/2 < 2/2x < 0/2...simplify
-9 < x < 0 <===
I am not for sure but I think 1.13*10-4
