X^2-4x+3=0 solutions <br>larger and smaller solutions ​
andrew11 [14]

Answer:

x = 3 or x = 1

Step-by-step explanation:

Solve for x over the real numbers:

x^2 - 4 x + 3 = 0

Subtract 3 from both sides:

x^2 - 4 x = -3

Add 4 to both sides:

x^2 - 4 x + 4 = 1

Write the left hand side as a square:

(x - 2)^2 = 1

Take the square root of both sides:

x - 2 = 1 or x - 2 = -1

Add 2 to both sides:

x = 3 or x - 2 = -1

Add 2 to both sides:

Answer: x = 3 or x = 1

Deacon Middle School
5x = number of boys
4x = number of girls
where x is some unknown number for now

(number of boys)+(number of girls) = 270 students total
5x+4x = 270
9x = 270
x = 270/9
x = 30

Since x = 30, this means
number of girls = 4x
number of girls = 4*30
number of girls = 120

There are 120 girls at Deacon Middle School

-----------------------------------------

Similarly, for Meadow Middle school
number of boys = 4y
number of girls = 5y
for some number y

(number of boys) + (number of girls) = 180 students total
4y+5y = 180
9y = 180
y = 180/9
y = 20

making,
number of girls = 5*y
number of girls = 5*20
number of girls = 100

so there are 100 girls at Meadow Middle School

-----------------------------------------

In summary so far, there are...
120 girls at Deacon Middle School
100 girls at Meadow Middle School
In total 120+100 = 220 girls from both schools

This is out of 270+180 = 450 students total

Divide the two values (220 and 450) to get
220/450 = 22/45

The final answer is 22/45
It cannot be reduced further as there are no common factors (other than 1) between 22 and 45

The area of a rectangle is 42 square inches and one side is 12 inches long. Find the perimeter of the rectangle. Show your work.
LenaWriter [7]
I might not be correct but i think Perimeter=31. Since the problem tells me that the area is 42 square inches i divided the given area (42 inches) by the given side length (12 inches), and I got 3.5. I did this because the formula for area is a=lw therefore 12×3.5=42 inches. Now that I know the missing measurement of the other side length, I can plug the numbers I have into either one of these equations. 
P=SIDE++SIDE+SIDE+SIDE OR P=2(length)+ 2(width). Please let me know whether or not you understand or have any other questions I will be more than happy to answer. Later when you reach 9th grade and become a freshmen you will learn theorems that will help make it a little bit easier and they will also remove A LOT of the algebraic work that's required to solve questions such as this one. My name is Takira and I go to LaGuardia High School for Performing Arts. Please let me know if you have any more questions.
