The answer id 12 meters.divide -2x^2+20x+48 by 2 to get x alone and then umbrella
Answer:
We have 6( n - 24 ) = 8N;
Then 6n - 144 = 8N;
-144 = 8N - 6N;
-144 = 2N;
N = (-144)÷2;
N = - 72;
Step-by-step explanation:
D : c = 33 : 22
where d is the number of dogs and c is the number of cats;
and: d + c = 3030
33 c = 22 d / : 11
3 c = 2 d
From the other equation: c = 3030 - d
3 * ( 3030 - d ) = 2 d
9090 - 3 d = 2 d
5 d = 9090
d = 9090 : 5
d = 1818
Answer: There are 1818 dogs in the shelter.
