Alright, we're in the home stretch here :) All you need to remember is that i² = -1. Otherwise, it is the same as FOIL
(3-2i)(1+7i)
3-2i+21i-14i² ← Replace the i² with -1, then simplify like numbers
3+19i+14
17+19i or C

Answer: 20m³
Step-by-step explanation:
From the statement
V <> 1/p --------------------- 1
V = k/p --------------------- 2
K. = VP ---------------------- 3
V = 60 , p = 1
To find k which is a constant, we put those values in equation 3
K = 60 x 1
= 60.
Now from the second statement
V = k/p where p is 3
Therefore,
V = 60/3
= 20m³
X=82
it adds up to 180 so (x+6)+(x+10)=180
Answer:
17.5m
Step-by-step explanation:
958.2 minus 23.9= 934.3
934.3 minus 951.8= - 17.5
the negative doesnt matter so you can take that away so the answer is 17.5
