I think B not 100% sure though
This is a linear equation y = mx, where:
m= slope or reading rate:
x = the number of minutes
y = the number of pages read.
So the equation becomes: y = 4.5.x
How many minutes it will take to read 90 pages (y):
90 = 4.5.x or x = 90/4.5 and x = 20 minutes
So the ordered pair will be (20,90)
Multiply 18 * 3 and 20 * 3
18*3 = 54
20 * 3 = 60
Length = 54 cm ; Width = 60 cm
Area = L x W
54 * 60 = 3240
Area = 3240 cm
3a² - 2a - 4 + 2a -3a² + 5
Put all the like terms together
= 3a² -3a² + 2a - 2a + 5 - 4
Combine like terms
= 1
Answer: 1
Use the tangent to find the angle.
Then translate that into a bearing.
