What the above statement is saying is:
If the number is 4, find the difference between the square of the number (the number is 4) and the number itself (the number is still 4).
The square of the number is:
The number^2
= 4^2
= 4 × 4
= 16
The difference between the square of the number and the number is:
The number^2 - The number
= 16 - 4
= 12
Hope this helps! :)
Answer:
the answer is 10 to the 5th power
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
I think it's A because it mostly multiplies then adds and subtracts so you get your answer doing this
Answer:
The x is the domain and the y is the range. It's still a function
Step-by-step explanation:
Answer:
x = 1/2 , x = -1/2
Step-by-step explanation:
Given equation;
169x² - 42.25
Find:
Solution of equation using square root
Computation:
169x² - 42.25
We know that 13² = 169 and 6.5² = 42.25
So,
[13x]² - [6.5]²
a² - b² = (a + b)(a - b)
So,
[13x]² - [6.5]² = [13x + 6.5][13x - 6.5]
So,
13x + 6.5 = 0 , 13x - 6.5 = 0
x = 6.5 / 13 , x = -6.5 / 13
x = 1/2 , x = -1/2
