A = 1/2 bh
A = 1/2 • (6x + 4)(x-7)
Use FOIL to multiply the binomials
A = 1/2 • 6x^2 - 3x - 28
Multiply the (1/2) in
A = 3x^2 - 3/2x - 14
Final answer!
Answer:
1/3?
Step-by-step explanation:
Hi there! 3 feet = 1 yard, 12 inches = 1 foot and 36 inches = 1 yard. All we have to do is change them up into different units by doing a bit of multiplication, division, maybe mental math, and even proportions if you know how to do them. Regardless on what you do, if you do it correctly, here are what your answers should be for each unit.
Inches
Carol: 42 inches
Tino: 30 inches
Baxter: 54 inches
Feet:
Carol: 3.5 feet
Tino: 2.5 feet
Baxter: 4.5 feet
Yards:
Carol: 1 1/6 yards
Tino: 5/6 yards
Baxter: 1 1/2 yards
Median: 23.5
12 and 35 are in the middle so you add them and divide by 2, leaving you
23.5 as your median.
Mean: 41.3
Add all numbers together and divide the sum by the number of numbers added. So all numbers added together equals 413. Divide by ten the nuber of numbers added. 413/10 equals 41.3.
Mode: 99
The number that appears most often. In this case, 99 would be the mode.
Range: 98
The lowest number subtracted from the highest number. 99-1 equals 98.
IQR: 84.75
Hope this helped! :)
The straight line ON has the following equation :
(x - 18)/(x - 0) = (y - 12)/(y - 0)
Where (18,12) are coordinates of N and (0,0) are coordinates of O.
x - 18/x = y - 12/y
-18y = - 12x
y =12x/18 - - - - - (a)
The coordinates satisfy equation (a) are (7.5, 5)
Therefore D is the correct answer.
Good luck
