Answer:
The area of trapezoid is 32cm².
Step-by-step explanation:
Given that the area of trapezoid formula is A 1/2×(a+b)×h where a, b represents length and h is height :
The Mean Absolute Deviation (MAD) Is 13.8
Put it in the form
ax^2 + bx + c = 0
use the quadratic formula
x = [ -b + sqrt( b^2 - 4 ac ) ] / 2a
x = [ -b - sqrt( b^2 - 4 ac ) ] / 2a
7v^2 - 7v - 22 = 0
a = 7
b = -7
c = -22
v = [ 7 + sqrt ( 49 - 4 * 7 ( -22) ] / 2 * 7 = 2.34
v = [ 7 - sqrt ( 49 - 4 * 7 ( -22) ] / 2 * 7 = -1.34
Answer:
Step-by-step explanation:
Subtract 2 from both sides
mutliply both sides by -4, flip the inequality
Add 2x on both sideds
Subtract 8 from both sides
Divide both sides by 6
