Answer: We will see in the next example how using the Quadratic Formula to solve an equation with a perfect square also gives just one solution. Solve 4{x}^{2}-20x=-25
Step-by-step explanation:
If you would like to know what is the following expression in the simplest form, you can calculate it like this:
If you 24v / 3v divide by v, you will get 24 / 3. Now, if you divide 24 by 3, you will get 8.
The simplest form of 24v / 3v would be 8.
Answer:
Mother: 40 years old
Rakhi: 15 years old
Step-by-step explanation:
Solution :
Let present age of Rakhi = x years
Present age of Mother = 4x
5 years later
Age of Rakhi =x+5
Ag of Mother =4x+5
Given 4x+5=3(x+5)
4x−3x=15−5
⇒x=10
Mother's age =4x=40 years
Plug 10 in for x to find Rakhis age
Answer: C
Step-by-step explanation: You have to plug in the values to see if it matches the values on the table of values
