Erm
x+y=6
xy=12
x+y=6
y=6-x
sub back
xy=12
x(6-x)=12
6x-x^2=12
x^2-6x=-12
x^2-6x+12=0
quadratic formula
for
ax²+bx+c=0

for
x²-6x+12=0
a=1
b=-6
c=12
and remember that √-1=i






x=3+/-i√3
the numbers are 3+i√3 and 3-i√3
no real numbers tho

Answer:
5 units
Step-by-step explanation:
Image of the trapezoid is attached.
To find the height of the trapezoid (image attached), let's take the formula for area of a trapezoid.
The formula for area of a trapezoid is:

Here, a and b represents the bases of the trapezoid.
a = 6
b = 10
h which represents height is unknown.
A = 40
Substitute figures:



Solve for h:


The height of the trapezoid is 5 units
