A = 900
The area of a parallelogram can be found by taking its base (b) and multiplying by the height (h). The base has the measure of 33 +12 = 45 cm. Now, you just need to find the height of the parallelogram. The height can be found by using the pythagorean theorem (

.
So, when simplified the height of the parallelogram will be found from

The height is 20 cm. The base is 45 cm. 45 x 20 = 900.
X=3, y=4
x=-2, y=9
Set x equal to anything, then isolate y to get the other number.
The answer is b. The paired chromosomes overlap of dna
The equation of a line that passes throug the point (x1,y1) and has a sloppe of m is
y-y1=m(x-x1)
the slope of paralell lines ar the same
y=3x+2
y=mx+b
m=slope
m=3
a point is (-2,0)
slope is 3
y-0=3(x-(-2))
y=3(x+2)
y=3x+6
the equation is y=3x+6
