Answer:
The order in which operations should be done is abbreviated as PEMDAS
Step-by-step explanation:
The order in which operations should be done is abbreviated as PEMDAS:
Parentheses denoted by '( )'
Exponents denoted as the power of a number '^'
Multiplication denoted as product of numbers '×'
Division denoted as dividing two numbers '÷'
Addition denoted as sum of two numbers '+'
and Subtraction denoted as difference of two numbers '-'
For example,
To solve using operation order we first solve parentheses ,
Then exponents,
then, multiplication,
now, division
now addition and then subtraction,
Thus, solving using operation order we find the value as 6.
To find <ABC, the first thing you would need to do is to find angle DBA and the value of x
As <DBE is a right angle, <DBE is on the same straight line as well,meaning that it would be 90° , a right angle as well.
It also mean that the total sum of the angles unknown would be 90°
To find x,we need to set up an equation:
(2x+14)+ (x+7) = 90
3x+21 = 90
3x = 69
x = 23
Thus,<ABC would be
(23)+7
=30°

F(x) = 2(x+6). If f(x) = 22, that means replace f(x) with 22
22 = 2(x+6) or
22 = 2x + 12 . Now solve this equation with the variable x:
2x = 22 - 12
2x = 10
x = 5 (Answer B)
