4+2(x+6)^2
6(x^2+12x+216)=0 [ {a+b}^2 = a^2+2ab+b^2 ]
6x^2 +72x+216=0
Put the value of x=(-3)
So ,
6x^2 +72x+36=0
6(-3)^2+72(-3)+216=0

Write the equation of a square root function that has been
shifted up 3 units and right 1 unit and contains the point
(5,7).
The equation of the square root function is g(x) = √(x - 1) + 3
How to determine the equation of the square root function?A square root function is represented as
f(x) = √x
The transformation rule is given as
Shifted up 3 units and right 1 unit
This can be represented as
(x - 1, y + 3)
So, we have
g(x) = f(x - 1) + 3
This gives
g(x) = √(x - 1) + 3
From the question, we have
It contains the point (5,7).
This means that
g(5) = 7
So, we have
g(5) = √(5 - 1) + 3
Evaluate
g(5) = 7
Hence, the equation of the square root function is g(x) = √(x - 1) + 3

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 42 N acts on a certain object, the acceleration of the object is 7 m/s^2. If the acceleration of the object becomes 2 m/s^2, what is the force?
The force on the object will be 12 N.
We have a moving object.
We have to determine the force on object when the acceleration of the object becomes 2 m/s².
What is the need of Force in real Life? How is it calculated ?Force is necessary to bring around a change in the state of the body. Either from rest to motion or motion to rest. It can be calculated using the formula-
Force (F) = mass (m) x acceleration (a)
According to the question -
When a force of 42 N acts on the object, then using the formula of force -
F = m x a
42 = m x 7
m(Object) = 6 Kg
When the acceleration of the object becomes 2 m/s², then -
F = m(object) x a
F = 6 x 2 = 12 N
Hence, the force on the object will be 12 N.

what is simple intrest
Simple Interest can be defined as a method of calculating interest for a some principal amount over a period of time.
When we borrow money or take a loan , and when we pay back the loan some money is charged based in the amount borrowed and time period the loan is taken ,
that money charged is called as Simple Interest .
Simple Interest can be calculated using the formula
SI=(PxRxT)/100
where, P=principal , R=rate of interest , t=time taken
The main difference between the Simple Interest and Compound Interest is the in Simple interest the principal is fixed whereas in Compound Interest the principal keeps on varying with time .
For Example : John borrowed $200 from Smith at 10% rate of interest for 5 years .
So the Simple Interest that John has to pay Smith will be
SI=(PxRxT)/100
SI=(200x10x5)/100
SI=10000/100
SI=$100
So apart from principal amount $200 John has to pay extra $100 as interest , Total John will be paying $300 to smith in return.
Therefore , Simple Interest is defined .

According to the given question.
We have the vertices of a quadrilateral abcd such that a(1, 0), b(5, 0), c(7, 2) and d(3, 2).
As we know that, a parallelogram is a two-dimensional geometrical shape, whose sides are parallel to each other. It is a type of polygon having four sides (also called quadrilateral), where the pair of parallel sides are equal in length.
Since, we have to prove that the given quadrilateral is a parallelogram by using slope. From the definition of the parallelogram we can say that, the opposite sides of the parallelogram are parallel to each other.
Now,
slope of side ab = 0-0/(5 -1) = 0
slope of side dc = 2 -2/(3-7) = 0
slope of the side ad = 2 -0/(3 -1) = 1
slope of the side bc = 2 -0/(7 -5) = 1
Here, the slopes of the opposite sides ab and dc, and ad and bc are equals and we know that when the slope of two line are equals then the lines are parallel to each other.

What is an Inequality in Mathematics ?An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
Let for x number of checks per month the simple checking plan cost less.
For No frills plan -

Therefore, for x checks, it will cost - $0.25x
For Simple Checking plan -
Fixed monthly charges - $5
Charges per check - $0.50
Therefore - for x checks - $5 + $0.50x
Now - for Simple Checking plan to cost less than No frills plan -
5 + 0.05x < 0.25x

Answer: -8 45/56
Step-by-step explanation:
Write an equation of the line that is parallel to y = 16 and passes through point (-7, 43).
The required equation of the line is y = 43 which is parallel to line y = 16 and passes through the point at (-7, 43).
What is the slope of the line?The slope of the line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
First, we have to determine the slope of the line y = 16 by placing it into a slope-intercept form:
y = 16
Therefore, the slope of the line is m = 0
Since the required line passes through the point at (-7, 43).
Let the line (y - y₁) = m(x -x₁ )
Here x₁ = -7, y₁ = 43
Substitute the values in the equation,
So, y - (43) = 0(x-(-7))
⇒ y - 43 = 0
⇒ y = 43
Hence, the required equation of the line is y = 43 which is parallel to line y = 16 and passes through the point at (-7, 43).
