The given expression is
We have to find the discriminant first . And for that, first we need to move whole terms of the left side to right side, that is
The formula of discriminant is
Substituting the values of a,b and c, we will get
And since the discriminant is greater than 0, or it is positive so we have two real roots.
Therefore the correct option is B .
So 45 in 30mins
we ususlly want to make the smallest number equal to one or as close to one as possible so
45/30=3/3 times 15/10
3/3=1
1 times 15/10=15/10
15/10=5/5 times 3/2
5/5=1
1 times 3/2=3/2
3 divided by 2 is 1.5

Answer:
8
Step-by-step explanation:
whatever was done to y needs to be done to x.
in this case (y) was 2x so you need to 2x (x) making 4 into 8
Answer:
The correct answer is: Option D: 8
Step-by-step explanation:
Given that she spent $208 on the sewing machines
And
the equation for profits to break even is:
208 + 10x = 36x
In order to find the number of purses to break even, we have to find the value of x
So,
Subtracting 10x from both sides
Dividing both sides by 26
The number of purses is 8
Hence,
The correct answer is: Option D: 8
Answer:
216 meter cubes
Step-by-step explanation:
The part where you got 1728 as the volume for the cube is right, but the question is asking how many 2x2x2 meter cubes can fit, meaning that you must find the volume of the meter cubes and divide the cube with a volume of 1728 to get the amount of cubes. In this case 2^3 is 8, so 1728 divided by 8 is 216, which means that 216 meter cubes with 2x2x2 dimensions can fit inside the larger cube.
Hope this helps! :D
