Answer:
4(2x-3)(2x+3)
Step-by-step explanation:
The first thing you would do is find the greatest common factor (the biggest number that goes into both of them.
Common factors
1,2,4
So the greatest common factor would be 4 so then you would divide both numbers by 4 and bring it to the outside like so.
4(4x2 - 9)
then you would take it out to where it would multiple to get the same number, like this.
4(2x-3)(2x+3)
18- answer is 120
to find this:
first find the remaining angle in ABF
180-(55+40)=180-95=85
F has two angles. if F1 is 85 F2 is 85,too.(coterminal angles)
now you can find the interior angle of CDF
180-(35+85)=180-120=60
the you should find the exterior angle(exterior angle + interior angle =180)
180-60=120
x=120
20
x=48
y=82
ABC is parallel to EF
so to find x: 180-132=48
and for y:
180-((180-130)+48)=180-(50+48)=180-98=82
hope this helps
Was my answer correct...!?
Answer:
??? and 0
Step-by-step explanation:
Ok I don't know about the first one but all I know is that it has 0 reflectional symmetries. Apologies for that but I wish you luck on your work and hopefully this somewhat helps a bit. ;-D
