Your answer is C:8. You can draw six shapes and divide the shapes in 4 pieces. Then you would count how many 3/4 are there.
A^2 - b^2 ...difference of squares
so
9m^4 - 49n^6 = (3n^2)^2 - (7n^3)^2
answer
C. 9m^4 - 49n^6
Answer:
A = 48 square units
Step-by-step explanation:
The dimensions between two markings on the coordinate plane = 2 unit
The trapezoid is located sideways
The area of a trapezoid, A = ((a + b)/2) × h
Where;
a = The long base side
b = The short base side
h = The height
The long base side length AT = 4 space between markings = 4 × 2 units = 8 units
The short base side length SR = 2 space between markings = 2 × 2 units = 4 units
The height, h = 4 space between markings = 4 × 2 units = 8 units
The area of the trapezoid, A = ((4 unit + 8 unit)/2) × 8 unit = 48 square units.
I’m not sure on this one but what I think you need to graph is the different floors on the Y axis and the time on the X axis. For the time, label it as 1 minute, 1m 30 secs, 2 mins, 2 mins 30 secs and so on. Then you can plot the points. Don’t take my word for this one because I’m not too familiar with these. Sorry I couldn’t be as helpful ~~
