To solve quadratics, the most correct and effective way, in my opinion, is the quadratic formula:
<span><span>
Plugging it in, we get:
</span></span>
So the final answer is:
and
The height is 4 cm and the base is 8 cm.
Make bottom numbers same
convert to improper fraction
1 and 5/6=1+5/6=6/6+5/6=11/6
1/2 and 11/6
2 times 3=6
1/2 times 3/3=3/6
1/2+11/6=3/6+11/6=(4+11)/6=14/6
answer is A
X+10=18. |-10 from both sides
x+10-10=18-10
x=8
