Answer:
Angle DCB is Equal to 78
Step-by-step explanation:
4x+2 + 3x+3 =180
7x +5=180
7x=175
x=25.
Then put the x in the 3x+3
3(25) +3 = 78
so DCB = 78

Step-by-step explanation:
Compound Interest Formula

A = final amount
P = initial investment
r = interest rate
n = number of times the rate is applied during a time period
t = number of times the time period has elapsed

Just use the order of operations. PEMDAS, parentheses, exponents, multiplication, division, addition and subtraction.
In the first problem 2 + 6*3^2, there are no parentheses, so next would be exponents.
There is an exponent so you do that first.
3^2 = 9
Now we have 2 + 6*9
Multiplication is next and it is in the problem, so we do 6*9 = 54
So now we have 2 + 54 which equals 56.
