Trapezoid Area = (Bases / 2) * Height
20 cm² = 5 * Height
Height = 4 cm
7(x + 2) = 6(x + 5)
7x + 14 = 6x + 30 |subtract 14 from both sides
7x = 6x + 16 |subtract 6x from both sides
x = 16
This is the symmetric property, for you divide 9 to both sides to get x, instead of adding (addition property of equality)
So symmetric property should be your answer
Hope this helps
Answer:
Option A: (-10,0)
Step-by-step explanation:
The given equation of the parabola is in the form of 
where the focus is located at 
. Therefore, the focus of the parabola is 
.
142=120% of x
120% of x= 1.2x
142=1.2x
142/1.2 = 1.2x/1.2
x= 118.33
The unknown number should be 118.33, rounded to 118 or so.
