First let's review how to find the surface area of a rectangular prism. Since the opposite faces have the same area, we just need to find one of each pair of faces and multiply the result by 2.
One face in each pairs adds up to 6*4+2*4+2*6=24+8+12=44
Now we just need to multiply this by 2!
44*2=88 cm^2
I really hope my explanation helped, if there are any more question about this please ask me in the comments I will answer them.
The answers are:

Answer:
Around $9.19
Step-by-step explanation:
"1/4" basically means:
1/4 = 0.25
THus, we can say annnual interest rate is 5.25%
Converting to decimal, we have:
5.25/100 = 0.0525
To find annual interest, we have to multiply interest rate (0.0525) with principal amount (700), so annual interest would be:
700 * 0.0525 = $36.75
That would be earned in 1 year.
But the money is kept LESS than 1 year, 3 months to be exact. We know
3/12 = 1/4th year
So, 3 months is 1/4th of a year. So $36.75 in 1 year, 3 months would be 1/4th of that:

Rounding to 2 decimal places, that would be around $9.19
Do you realize that you have given out 50 points?
Step OneStart by subtracting 23 from both sides.
-3x^2 + 4x - 31 -23 = 0
-3x^2 + 4x - 54 = 0
This does not give you a real result. We'll solve it anyway
Step twobring out the quadratic equation and solve that
a = - 3
b = 4
c = -54

Considering the roots of function f(x), the correct statement is given by:
D. f has exactly two zeros of [0,4].
<h3>What are the roots of a function?</h3>
The roots of a function are the <u>values of x for which f(x) = 0</u>.
In this problem, we have that:
- f(2) = 0, hence x = 2 is a root.
- f(3) < 0 and f(4) > 0, meaning that between x = 3 and x = 4, there is a root of a function, as to go from negative to positive, it has to pass through f(x) = 0.
For values of x less than 2 on the interval, the function is never negative nor zero, hence there are no roots in that interval and option D is correct.
