Answer:
y=3x-2
Step-by-step explanation:
I believe that the equations answer is around 1170. The answer to the equation is 1172
The angles of a 4 sided shape always add up to 360.
y + x + 190 - y + 70 = 360
x + 190 + 70 = 360
x + 260 = 360
x = 100
To solve this we are going to use the formula for the area of a circle:
where
is the area of the circle
is the diameter of the circle
We know from our problem that the area of our circle is 10 inches long, so
. Lets replace that value in our formula to find
:
We can conclude that the correct answer is: 78.54 square inches, or in centimeters: 506.7 square cm.
5x2=−30x−65
Subtract -30x-65 from both sides.
5x2−(−30x−65)=−30x−65−(−30x−65)
5x2+30x+65=0
Use quadratic formula with a=5, b=30, c=65.
x = −30±√−400 / 10
No solution.
