Answer:
I'll assume that u forgot to put the square in the second parenthesis
(2x^2-2x-7) . simplified
Step-by-step explanation:
(8x^2+9)-(6x^+2x+2) distribute negative sign
8x^2+9-6x^2-2x-2 . combine like terms
(2x^2-2x-7) . simplified
Answer: " 32.5 % " .
________________________________________________
→ " <u> 32.5 % </u> of 60 is 19.5 . "
________________________________________________
Step-by-step explanation:
________________________________________________
What percent of 60 is 19.5 ?
n/100 * 60 = 19.5 ; Solve for "n" ;
60n / 100 = 19.5 .
6n/10 = 19.5 ;
(0.6) n = 19.5 ;
Multiply Each Side of the equation by "10" ; to get rid of the "decimal" on each side ;
10 * (0.6)n = 19.5 * 10 ;
6n = 195 ;
Divide each side of the equation by "6" ;
to isolate "n" on one side of the equation;
& to solve for "n" ;
6n / 6 = 195 / 6 ;
to get:
_______________________________________________
n = 32.5 .
________________________________________________
The answer is: " 32.5 % " .
________________________________________________
" <u> 32.5 % </u> of 60 is 19.5 . "
________________________________________________
It would have to be c because if n - any number then its c
ANSWER
Ending Balance = $6000
EXPLANATION
We want to use simple interest to find the ending balance.
This means that we have to find the interest and add it to the initial balance.
The formula for simple interest is:
where P = principal = $5000
R = rate = 5%
T = number of years = 4 years
So, the interest on that amount is:
So, the ending balance is the sum of the interest and the principal:
Ending Balance = 5000 + 1000
Ending Balance = $6000
