Use PEMDAS. Parenthesis, Exponents, Multiply, Divide, Addition, Subtraction.
So, you'd distribute 5 into the parenthesis, leaving you with 9+20x+20, then add like terms. 20x+29
7x3x2 and 7x6x1.
Hope this helps!
Given that f(x) is a function that represents number of hours required to travel, the domain of the function is: distance travelled in miles (x)
<em><u>Recall:</u></em>
- In a relation that is a function, the domain of the function is the set of input values (x-values).
- The range of the function is the set of output values (y-values or f(x)).
Thus, given that f(x) is a function that represents number of hours required to travel, therefore:
- x = input values (domain) = distance travelled in miles
- f(x) = output values (range) = number of hours.

Answer:
Step-by-step explanation:
take 52 degree as reference angle
using tan rule
tan 52=opposite/adjacent
1.27=x/21
1.27*21=x
26.67=x
26.9=x
Answer:
x 
Step-by-step explanation:
You move the decimal to the right of the first non-zero digit. Count the spaces you moved it, remembering the LARD rule, and that is the power of ten.
