Answer:
$1,110
Step-by-step explanation:
You have to use the interest formula to calculate how much each brother will have after a year.
A = P(1+r)^t
A = future/ending value
P = principle
R = interest rate
T = time (given in years)
Charles = 30,000(1+.025)^1 = 30,750
Brian = 30,000(1+.062)^1 =31,860
31,860-30,750=1,110
Brian will have $1,110 more than Charles after 1 year
The surface area for a cube is SA = 6(side times side).
So, SA = 6(15 times 15) is SA = 6(225), and that is 1,350.
The surface area of this cube is 1,350mm squared.
After factor by grouping we get
Step-by-step explanation:
We need to factor the term:
Taking c common:
Now making groups:
Now factorizing by groups:
So, after factor by grouping we get

Answer:
37
Step-by-step explanation:
Let the initial number be .
Initial number:
Units digit = y
Tens digit = x
The units digit of a 2-digit number is 1 more than twice the tens digit, then
Reversed number is
If the new number is 36 more than the original number, then
Simplify this equation:
Substitute into the equation
Initial number: 37
