What is the length of the third side of the window frame below?
A. 10 inches
B. 12 units
C. 16 units
D. 20 units
Answers
Answer:
20 units
Step-by-step explanation:
a^(2)+b^(2)=c^(2)
48^(2)+b^(2)=52^(2)
2304+b^(2)=2704
2304-2304+b^(2)=2704-2304
b^(2)=400
\sqrt(b^(2))=\sqrt(400)
b=20
therefore,20 is the length of the unknown side

Answer:
[tex]x = 0[/tex] and [tex]x = -2[/tex]
Step-by-step explanation:
[tex]\frac{x}{2} = \frac{{x}^2}{x-2}[/tex]
Use cross multiplying to solve the equation.
[tex]x(x-2) = 2({x}^2)[/tex]
[tex]{x}^2 - 2x = 2{x}^2[/tex]
[tex]2{x}^2-{x}^2+2x = 0[/tex]
[tex]{x}^2 + 2x = 0[/tex]
Now factor it.
[tex]x(x+2) = 0[/tex]
Now split into two equations:
Equation A:
[tex]x = 0[/tex]
Equation B:
[tex]x + 2 = 0[/tex]
[tex]x = 0 -2[/tex]
[tex]x = -2[/tex]
Therefore, the solutions are x = 0 and x = -2.

how do I solve −2(n− 9) + 4 using distributive property or combining like terms?
Answers
Answer:
Multiply the term outside of the parentheses by each term in the parentheses. To do this, you are essentially distributing the outer term into the inner terms. Multiply the term outside the parentheses by the first term in the parentheses. Then multiply it by the second term. If there are more than two terms, keep distributing the term until there are no terms left. Keep whatever operation (plus or minus) is in the parentheses

10.31%
Explanation:
This is the answer
friend bought the car in Lilburn with a percentage of 7% ie the price list of the car is $18483.75.
How do I calculate percentage?If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.The proportion therefore refers to a component per hundred.Per 100 is what the word percent means.The letter "%" stands for it.Percentage, which meaning "per 100," designates a portion of a total sum.The use of percentages is widespread and diverse.For instance, many statistics in the media, bank interest rates, retail discounts, and inflation rates are all expressed as percentages.For comprehending the financial aspects of daily life, percentages are crucial.The friend paid total of $19,875 for a car.
7% of 19,875 = 1391.25.
The list price of the car = 19,875 - 1391.25 = 18483.75

The number of years that Zach has been on the soccer team is 2 less than 5
times the number of years that Anderson has. In total, the boys have been on
the soccer team for 10 years. How long has each boy been on the soccer team?
Answers
Answer:
Brad has been on the team for 8 years. Apply that and that means that Anderson has been on the soccer team for 2 years.
Step-by-step explanation:
I dont know how to explain lol i made an equation and figured it out
Step-by-step explanation:
let x be the number of years that Zach has been on the soccer team and y the number of years Anderson has been on the soccer team.
So, reading our problem it seems that
x=5y-2
x+y=10
replacing x on the second formula we take that 5y-2+y=10
6y-2=10
6y=12
y=2
so x=5y-2=5*2-2=10-2=8
