The value of the equation is A = 4x² + 28x + 48
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
A = ( 2x + 6 ) ( 2x + 8 ) be equation (1)
Now , on simplifying the equation , we get
A = 2x ( 2x + 8 ) + 6 ( 2x + 8 )
On further simplification , we get
A = 2x ( 2x ) + 2x ( 8 ) + 6 ( 2x ) + 6 ( 8 )
A = 4x² + 16x + 12x + 48
A = 4x² + 28x + 48
Therefore , the value of A is 4x² + 28x + 48
Hence , the equation is A = 4x² + 28x + 48

===========================================================
Explanation:
You set the equations up properly. Nice work so far.
Let's add the equations straight down.
The x terms add to x+x = 2xThe y terms add to y+(-y) = y-y = 0y = 0, showing that the y terms cancel each other out and go away.The numbers on the right side add to 5+(-3) = 2After those three sets of addition operations, we are left with the equation 2x = 2. This solves to x = 1 after dividing both sides by 1.
-------------
Use this x value to find y
We can pick either equation. If we pick the first equation, then,
x+y = 5
1+y = 5
y = 5-1
y = 4
Or we could use the other equation instead
x-y = -3
1-y = -3
-y = -3-1
-y = -4
y = 4
Either way, we get the same y value when x = 1. This helps confirm we have the correct x value. A more thorough check would involve plugging (x,y) = (1,4) into both original equations and simplifying. You should get the same value on each side.
The value of x is 1 while y is 4 for the given set of constraints.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
Let's say the first number is x while the second is y
Now,
x + y = 5
x - y = -3
By adding
2x = 2
x = 1
So y = 5 - 1 = 4
Hence "The value of x is 1 while y is 4 for the given set of constraints".

A person runs at 35 m/s from a standstill. What is their acceleration after 5 sec?
Answer:
The acceleration is 7m/s^2
Step-by-step explanation:
Given
[tex]u = 0m/s[/tex] -- Initial Velocity
It is 0 because the person starts from a standstill
[tex]v = 35m/s[/tex] -- final velocity
[tex]t = 5s[/tex] -- time
Required
Determine the acceleration
This is calculated using Newton's first equation of motion
[tex]v = u + at[/tex]
Substitute values for v, u and t
[tex]35 = 0 + a*5[/tex]
[tex]35 = 0 + 5a[/tex]
[tex]35 = 5a[/tex]
Divide both sides by 5
[tex]\frac{35}{5} = a[/tex]
[tex]7 = a[/tex]
[tex]a = 7[/tex]
Hence, the acceleration is 7m/s^2

Julie’s mom paid $2.70 for 5 pounds of bananas at Supermart. Mario’s mom paid $2.60
for 4 pounds of Bananas at Market One. Write a division equation for each banana
purchase, and then decide which store had the better banana price.
Answer:
(Supermart) Equation 1 = $2.70÷5 lb = $0.54 per lb
(Market One) Equation 2 = $2.60÷4 lb = $0.65 per lb
Step-by-step explanation:
Since the unit price of bananas per lb in Supermart is less than the unit price of bananas per lb in Market One, Supermart has the better price.
Banana's rate at Supermart are better as compared to that of Market one.
What is division?Division is a process of splitting a number into equal parts.
Given is that -
Julie’s mom paid $2.70 for 5 pounds of bananas at Supermart. Mario’s mom paid $2.60 for 4 pounds of Bananas at Market One.Division equation for Julie's purchase -
5 pounds for $2.7
1 pound for $(2.7/5) = $0.54
Division equation for Mario's purchase -
4 pounds for $2.60
1 pound for $(2.6/4) = $0.65
The banana's rate at Supermart are better as compared to that of Market one.
Therefore, banana's rate at Supermart are better as compared to that of Market one.

Sarah works for a maximum of 40 hours per week. She needs to make at least $400 in order to cover her expenses. Her office job pays
$12 per hour and her babysitting job pays $10 per hour.
Which system of inequalities can be used to determine the number of hours she should spend working in office (x) and the number of
hours she should spend babysitting (/) to cover her expenses?
Answer:
x + y ≤ 40
10x + 12 y ≥ 400
x ≥ 0
y ≥ 0
Step-by-step explanation:
System of Inequalities
In order to model the situation stated in the problem, we'll call the following variables:
x = number of hours Sarah spends in the office
y = number of hours Sarah spends babysitting
She works for a maximum of 40 hours per week. This condition leads us to the inequality:
x + y ≤ 40
Her office job pays $12 per hour and her babysitting job pays $10 per hour.
She needs to make at least $400 per week in order to cover her expenses, thus:
10x + 12 y ≥ 400
Two obvious conditions could be added to the set of inequalities:
x ≥ 0
y ≥ 0
The system of inequalities is:
x + y ≤ 40
10x + 12 y ≥ 400
x ≥ 0
y ≥ 0
Which equation and solution can be used to solve this problem?
