Given : Expression
To find : Which operation should be completed first in the expression below?
Solution :
P - Parentheses
E - Exponent
D - Divide
M - Multiplication
A - Addition
S - Subtraction
In the first step we solve the bracket in the expression
So, we do subtraction i.e. 12-8=4
Therefore, option b is correct.
84
k(x+6)= 4x²+20
k(10)= k(4+6)= 4*4²+20= 64+20= 84
9.) .784 . 10) 0.29
$1884 I think
$1910 - 2.6% = $1884
Sorry if it is wrong!
