The volume of a box is the length x with x height. Because it is a cube all the sides are the same size, and it’s has three dimensions. That means you can calculate the length of one side by picking the root^3 (I don’t know what it is in English it is a square root with a 3 in the upper left corner) of 512. That gives you 8, so the sides are 8 inches Kong’s
Answer: Meghan spent $687.5 per year.
Step-by-step explanation:
Let x represent the amount of money that Scott spends per year for auto insurance.
Meghan spends 25% more each year for auto insurance than Scott. The value of 25% of the amount that Scott spends per year is
25/100 × x = 0.25 × x = 0.25x
Therefore, the amount that Meghan spends would be
x + 0.25x = 1.25x
If the amount that they spent together is $1237.50 per year, it means that
x + 1.25x = 1237.5
2.25x = 1237.5
x = 1237.5/2.25
x = 550
The amount that Meghan spent per year would be
1.25 × 550 = 687.5

ANSWER
the area of the trim around the glass in the window is option ( D)
i.e (x²+7x+3)
REASON
As given in the question
A window frame has a length of (5x+3) inches an a width of (x+6) inches.
As the shape of the window in the form of rectangle.
Formula
Area of the rectangle = length × breadth
put the value in the above equation
we get
Area of window = (5x+3)× ( x + 6)
= 5x² + 33x + 18 inches²
As given in the question
The area of the glass in the window is (4x²+26x+15) square inches.
Area trim around the glass in the window = area of the window - area of the glass.
put the value
we get
= ( 5x² + 33x + 18 ) - ( 4x²+26x+15)
= 1x²+ 7x + 3 inches²
therefore the correct option is (D)
Hence proved
