Answer:
-80
Step-by-step explanation:
We can write the quadratic as
ax^2 + bx+c
4x^2 +8x+9
a=4 b = 8 c=9
The discriminant is
b^2 -4ac
8^2 - 4(4)(9)
64 - 144
-80
Do 6/(3/4) equal 24/3(from multiplying the 6 and the 4), to get the answer: 8
274.4 gallons are remaining. You would need to find how many gallons of water was lost as steam. You would do 280*0.02, which is 5.6 gallons. Then, subtract 5.6 from 280, and you get 274.4
Answer:
The answer is 24 with remainder of 1
Step-by-step explanation:
First, solve the problem by seeing what number gives you 4 when multiplied by 2. That would be 2 (2x2=4)
you subtract 4 by 4 to get zero and bring down the nine
Then you see which number would get you close to nine without overlapping when multiplied by two. That would be 4 (2x4=8)
your answer would be 24 then you subtract 9 by 8 to get a remainder of 1
