Answer: 4 is 110 degrees and 3 and 1 is 70 degrees.
Step-by-step explanation: 4 is equal to 2 so 4 is 110 degrees 4
110 x 2 = 220 360 - 220 = 140/2 = 70 so 3 and 1 = 70 degrees
Answer:
48.983.
Step-by-step explanation:
(The parentheses are not balanced so I am assuming that there is a square parentheses at the end of the given expression).
Using order of operations (PEMDAS):
20.003 + [(30.1 + 5.75) - 6.87] Work out the inner parentheses first:
= 20.003 + [35.85 - 6.87] Now the outer parentheses:
= 20.003 + 28.98
= 48.983.
x = 7 and x = –7.
Solution:
Given data:
and 
To find the solutions when f(x) = 64.
Both are equations of f(x), so equate the given equations, we get
To isolate the constant term subtract 15 from both sides.
49 can be written as 7².
Taking square root on both sides of the equation, we get
x = ±7
The solutions to f(x) = 64 is x = 7 and x = –7.
Just use a calculator lol light work? =4
