Answer:
A
Step-by-step explanation:
Alright, this may come out weird on computer, but here we go.
First, you want to change this into a multiplication problem, with Keep change flip. So now it's (c^2-c-20/c^2-6c+5) * (3c-3/c^2-16). You then want to simplify some number down.
You can simplify the first part using the X game (not sure if you know this), but you put the c value at the top, and the B value at the bottom, and the two sides blank. These two values must add to equal the C value, but multiply to equal the B value, so you get -5 and 4 for the numerator of the top. Following this formula, and using difference of perfect squares, you'll end up with the following.
(c-5)(c+4)/(c-5)(c-1) * 3(c-1)/(c+4)(c-4)
You then need to cancel out your different groups, so you'll cancel out (c-5), (c+4), (c-1).
After all that, you'll end up with 3/c-4, so the answer is A.
Answer:
g = -2/3
Step-by-step explanation:
-g + 6 +2g = -4g - (-4)
g + 6 = -4g + 4
3g =-2
g = -2/3
Answer:
y = 97°
Explanation:
Opposite angles in a quadrilateral inscribed in a circle sum ups to 180°
So following the rule:
A + C = 180°
y + 83° = 180°
y = 180° - 83°
y = 97°
50 times 12 equals 600 minus 520 equals 80 bars left over.
Answer:
Lateral area of cone=pi *r*l
where r is radius
l is slant hieght
and pi can be 22/7 or 3.14
Step-by-step explanation:
- therefore, lateral area= 3.14*6*10
- =31.4*6
- 188.6m^2
