<em>(-17, -21)</em>
Step-by-step explanation:
When reflected across the x-axis, the signs of the x-coordinates will flip.
(A negative becomes positive, and a positive becomes negative.)
Hello, so the equation for the area of a trapezoid is A = (a+b)*(h/2)
In which, a is one of the bases, b is the other base, and h is the height. A is the Area. If you wanna solve for height, rearrange the equation to what h equals.
First divide (a+b) from both sides
A/(a+b) = h/2
Now multiply 2 on both sides
2(A/(a+b)) = h
Now you have it rearranged equal to just h. Plug in the values now.
2(3.9/(4+2.5)) = h
2(3.9/(6.5)) = h
2(.6) = h
1.2 = h

Answer:
x = -1/4 + sqrt(47)/4 i , -1/4 - sqrt(47)/4 i
Step-by-step explanation:
2x^2+x+6=0
using the quadratic formula
-b ±sqrt(b^2 -4ac)
--------------------------
2a
-1 ±sqrt(1 -4(2)(6))
--------------------------
2(2)
-1 ±sqrt( 1 - 48)
------------------
4
-1 ± sqrt(-47)
-------------
4
-1 ± sqrt(-1) sqrt(47)
-------------------------
4
remember sqrt(-1) = i
-1 ± i sqrt(47)
----------------
4
x = -1/4 + sqrt(47)/4 i , -1/4 - sqrt(47)/4 i
