Area=l*w
a=(x+9)(2x-1) <--- Use FOIL
a=2x²-x+18x-9
a=2x²+17x-9
Hope I helped :)
D= number of dimes
q= number of quarters
(Keep in mind, it's not the price, but the number of each)
0.1d+0.25q=74.35
d=q+5
0.1(q+5)+0.25q=74.35
0.35q+0.5=74.35
0.35q=73.85
q=211
d=216
Answer:
The correct option is;
Segment ED ≅ segment FD because segment EF is perpendicular to a radius of circle A
Step-by-step explanation:
All chords perpendicular to the radius of a circle are bisected by the radius of the circle
Given that DA can be extended to the circumference of circle A to form a radius of the circle A, and that DA is perpendicular to EF, therefore, DA bisects EF or EF is bisected into two equal parts by DA such that segment ED is congruent to segment FD
Therefore, the correct option is that segment ED ≅ segment FD because segment EF is perpendicular to a radius of circle A.

Answer:
cans extra food is needed to feed the second cat.
Step-by-step explanation:
Given:
When chad had one cat he needed to serve 1/5 of a can of cat food each day. Now that chad adopted a second cat he needs to serve a total of 11/2 cans each day.
Now, to find the extra food is needed to feed the second cat.
Food needed for one cat = 
Food needed for both one and second cat needed = 
Now, extra food needed to feed the second cat:
<u><em>Food needed for both one and second cat needed - food needed for one cat.</em></u>
<u><em /></u>
<u><em /></u>
<u><em /></u>
<u><em /></u>
Therefore, 
extra food is needed to feed the second cat.
