Answer:
No real
solution
Step-by-step explanation:
Firstly, let us check if we would be having a real solution
We start by rewriting the equation
We have this as;
8x^2 -25x + 24 = 0
We proceed to get the discriminant
Mathematically, we have this as;
D = b^2 - 4ac
b is the coefficient of x which is -25
a is the coefficient of x^2 which is 8
c is the last number which is 24
So we have;
D = (-25)^2 - 4(8)(24)
D = 625 - 768 = -143
Since the value of the discriminant is negative, there cannot be real roots
What we have as solution are complex roots

Answer:
B
Step-by-step explanation:
given the trinomial
15x² + 11x - 12
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 15 × - 12 = - 180 and sum = + 11
the factors are + 20 and - 9 , since
+ 20 × - 9 = - 180 and + 20 - 9 = + 11
use these factors to split the x- term
15x² + 20x - 9x - 12 ( factor the first/second and third/fourth terms )
= 5x(3x + 4) - 3(3x + 4) ← factor out (3x + 4) from each term
= (3x + 4)(5x - 3)

Answer:
The answer to your question is Area = 9 3/8
Step-by-step explanation:
Data
length = 3 3/4 cm
width = 2 1/2 cm
Process
1.- Write the equation of the Area of a rectangle
Area = length x width
2.- Convert the values to improper fractions
3 3/4 = (12 + 3)/ 4 = 15/4
2 1/2 = (4 + 1) / 2 = 5/2
3.- Substitution
Area = (15/4)(5/2)
4.- Simplification
Area = 75/8
5.- Convert to a mixed fraction

6.- Result
Area = 9 3/8
y=-5/4x+3.5
4y+10.6=-5x
Answers
y = -5/4x + 7/2
4y = -4x + 14
make both equations equal 4y:
4y + 10.6 = -5/x
4y = -5/x -10.6
this means that:
-4x + 14 = -5/x - 10.6
rearrange to find x:
[multiply by x]
-4x^2 +14x = -5 - 10.6x
4x^2 - 14x + 10.6x + 5 = 0
4x^2 -3.4x + 5 = 0
use the quadratic equation: x = (-b ± √(b^2 - 4*a*c)) / 2a
for this equation, a = 4, b = -3.4 and c = 5
write the answer in the form (x - answer one) (x - answer two)
this will give either two answers. Input these into the equation 4y = -4x +14 to find the coordinates.
To find the distance between these two points:
distance = √(change in x) + (change in y)
Final answer:
To find the distance between two points using given equations, solve the equations simultaneously to find the coordinates of the points and then use the distance formula.
Explanation:
To find the distance between two points using the given equations, we first need to find the points of intersection. We can do this by solving the given equations simultaneously to find the values of x and y. Once we have the coordinates of the two points, we can use the distance formula to find the distance between them.
- First, solve the given equations simultaneously to find the values of x and y.
- Substitute the values of x and y into the distance formula: d = √((x2 - x1)^2 + (y2 - y1)^2).
- Calculate the distance using the given formula.

8 pints = 1 gallon.
1 pint = 1/8 gallon
12 pints = 12*(1/8)
12 pints = (12/8) gallons
= 3/2 = 1.5 gallons.
Since the bucket is 5 gallon capacity, It can hold:
5 - 1.5
= 3.5 gallons more.
But 1 gallon is = 4 quarts.
3.5 gallons = 3.5 * 4 = 14 quarts more.
