Answer:
a.) 2(2x)+2(4x-3)
b.)2(2x)+2(4x-3)=42
Step-by-step explanation:
b.)2(2x)+2(4x-3)=42
distribute
4x+8x-3=42
add the like terms
12x-3=42
move the -3 by adding to both sides
12x=45
divide both sides by 12
12x/12=45/12
x=3.75
and to make sure it's right, plug x into the equation.
2(2(3.75))+2(4(3.75)-3)=42
now multiply/add/subtract everything.
2x2x3.75=15 (This was the 1st set of parenthesis)
2x4x3.75-3=27 (This was the 2nd set of parenthesis)
15+27=42
42=42
Given number = 0.44
Find how many times the value of the hundredths place digit to the value
of the tenths place digit.
=> Since this is a decimal number, I believe, the value you mean is
tenths and hundredths, not tens and hundreds.
Now, how many times is the value of each digit differs from each other:
The answer is 10 times
=> 4 hundredths x 10 = 4 tenths
=> 0.04 x 10 = 0.4, which is correct

Answer:
20/3
Step-by-step
(base1+base2)/2 * height = area of a trapezoid
64/12=16/3
16/3*2 = 32/3
32/3-4 = 20/3
