The surface area of the rectangular prism is 544 cm^2.
There are 3 pairs of different rectangles that form the rectangular prism.
If we find the area of each and add them up, we will have the surface area.
Here are the 3 pairs of rectangles:
6 x 16 = 96
8 x 16 = 128
6 x 8 = 48
2(96) + 2(128) + 2(48) = 544
Answer:
The amplitude is 4
Step-by-step explanation:
Recall that the amplitude of a harmonic form like this one based on the cosine function is the absolute value of the coefficient that multiplies the function. In our case that coefficient is 4.
So the amplitude of this function is "4".

Answer:
x = -2
Step-by-step explanation:
You would first distribute.
<u>6(3x + 7)</u> = <u>-5(4x - 3)</u> - 49 → 18x + 42 = -20x + 15 - 49
We can then calculate difference of 15 and 49.
18x + 42 = -20x <u>+ 15 - 49</u> → 18x + 42 = -20x -34
We can now move the variables to one side of the equation and the numbers on the other side.
18x + 20x + 42 - 42 = -20x + 20x - 34 - 42 → 38x = -76
Then, divide.
38x ÷ 38 = -76 ÷ 38 → x = -2
