Answer:
25(x+2)(x−2)
Step-by-step explanation:
The solution is A = 25 ( x - 2 ) ( x - 2 )
The equation to the expression is given as A = 25 ( x - 2 ) ( x - 2 )
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 = 25x² - 100 be equation (1)
On simplifying the equation , we get
Taking 25 as the common factor of the equation , we get
A = 25 ( x² - 4 )
Now , ( x² - a² ) = ( x + a ) ( x - a )
So , the value of ( x² - 4 ) can be simplified as
A = 25 ( x + 2 ) ( x - 2 )
Therefore , the value of A is 25 ( x + 2 ) ( x - 2 )
Hence , the equation is A = 25 ( x + 2 ) ( x - 2 )

the sum of two numbers is 5 and difference of their square is 5 find the difference if number
Answer:
x+y=5...i
x²-y²=5...ii
from i, x+y=5
x=5-y...iii
substitute iii in ii
(5-y)²-y²=5
25-2y²=5
2y²=20
y²=10
y=✓10
put y=✓10 in i
x+✓10=5
x=5-√10

Ayden earned a grade of 89% on his multiple choice history final that had a total of
200 problems. How many problems on the final exam did Ayden answer correctly?
Answer:
178
Step-by-step explanation:
Method 1: Set up a proportion
Set up an equation of the form:
\frac{\color{red}{\text{part}}}{\color{orange}{\text{whole}}}=
whole
part
=
\,\,\frac{\color{blue}{\text{percent}}}{100}
100
percent
Assign the variable xx to the unknown value:
\color{red}{x}=
x=
\,\,\color{red}{\text{part}}
part
The question asks what \textit{part}part of the total questions is 89%
Substitute the known values with the numbers given in the problem, and the unknown value with xx:
\frac{\color{red}{x}}{\color{orange}{200}}=
200
x
=
\,\,\frac{\color{blue}{89}}{100}
100
89
Solve for xx:
100\cdot\color{red}{x}=
100⋅x=
\,\,\color{orange}{200}\cdot\color{blue}{89}
200⋅89
Cross multiply
\frac{100x}{100}=
100
100x
=
\,\,\frac{17800}{100}
100
17800
Divide both sides by 100
178
Simplify
Method 2: Convert to decimal and multiply
{89}{100}=0.89
89%=
100
89
=0.89
Move decimal 2 places to the left
{Multiply result by the total:}
Multiply result by the total:
0.89{200}=
0.89⋅200=
178
