The quadratic value equation is solved and x = 3 , x = 4
What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
x² - 7x + 12 = 0
On simplifying , we get
x² - 3x - 4x + 12 = 0
On factorizing , we get
x ( x - 3 ) - 4 ( x - 3 ) = 0
Taking the common factors in the equation , we get
( x - 4 ) ( x - 3 ) = 0
So , the two values of x are
x = 4 and x = 3
Hence , the quadratic equation is solved

If m\angle VXW=28\degreem∠VXW=28°, what is the measure of arc VW?
Answer:
m(arc VW) = 56°
Step-by-step explanation:
m∠VXW = 28°
By inscribed angle theorem,
"Length of intercepted arc measures the double of the inscribed angle"
m(arc VW) = 2m(∠VXW)
m(arc VW) = 2(28°)
m(arc VW) = 56°
Therefore, measure of arc VW is 56°.

If
f (x) = x^2 - 4
what is the average rate of change from x = 3 to x = 5?
Answer:
The average rate of change is 8
Step-by-step explanation:
Mathematically, we have the average rate of change over a given interval as;
f(b) - f(a)/b-a
Where the interval is [a,b]
With respect to this question, a = 3 and b = 5
f(a) = f(3) = 3^2 - 4 = 9-4 = 5
f(b) = f(5) = 5^2 - 4 = 25-4 = 21
Thus, the average rate of change over the intervals will be;
(21-5)/(5-3) = 16/2 = 8
find the length of a missing side of the triangle around your nearest tenth
Using the Pythagorean theorem:
14^2 = 8^2 + x^2
196 = 64 + x^2
Subtract 64 from both sides:
132 = x^2
Take the square root of both sides:
X = 11.49
Rounded to nearest tenth = 11.5
Answer:
missing side = 11.5
Step-by-step explanation:
[tex]a^{2} = c^{2} - b^{2}[/tex]
[tex]a^{2} = 14^{2} - 8^{2}[/tex]
[tex]a^{2} = 196 - 64[/tex]
[tex]a^{2} = 132[/tex]
[tex]\sqrt{a^{2} } - \sqrt{132}[/tex]
a = 11.489
round to the nearest tenth:
11.489 = 11.5

A countertop is 11 feet long and 4 fee t wide.
What is the area of the countertop in square meters? Use the conversion 1 foot = 0.305 meter. Round your
final answer to 2 decimal place
Answer:
4.09m^2
Step-by-step explanation:
A countertop is 11 feet long and 4 fee t wide.
Using the conversion
1foot = 0.305 meter
11fet = 11(0.305)
11feet = 3.355 m
4 feet= 4 * 0.305
4feet = 1.22m
Area of the countertop = Length * Width
Area of the countertop = 3.355 * 1.22
Area of the countertop = 4.0931m^2
Hence the required area is 4.09m^2 to 2 decimal places

"Solve the linear equation for y" 14x= -5y (-) 11
Answer:
y = -4/5x - 11/5
Step-by-step explanation:
4x = -5y (-) 11
4x = -5y - 11
-5y = 4x + 11
5y = -4x - 11
y = -4/5x - 11/5
