Let's call the lesser number x and the other one x+8
Explanation:
The product x⋅(x+8)=240→
Or: x2+8x=240→
We can rework this by subtracting 240 from both sides:
x2+8x−240=0
Now we factor −240 into two factors that add up to 8
After some trying we find 20and−12
The equation turns into
(x+20)(x−12)=0
→x=−20orx=12
So the pairs of numbers will be:
−20and−12 or +12and+20
Answer:
It's option d.
Step-by-step explanation:
The line y = x + 2 has domain x < 2 (because of the clear circle.)
The lines y = x + 1 has domain x ≥ 2. ( because of the filled circle).
Answer: $ 200,000
Step-by-step explanation: The 6000 is 3% of the original price, so 6000/3 = x/100. To find the price of the home we will need to cross multiply and divide.
6000/3 = x/100
6000 * 100 = 600000
600000 / 3 = 200,000

Step-by-step explanation:
The question is incomplete, as the 8 expressions are not given.
The general explanation is as follows
As complex as an expression may seem, you have to simplify each expression until it cannot be further simplified.
Then you categorize each result, depending on if it equals 
or not
Take for instance:
Using law of indices:
---- equivalent
Factorize the numerator
Cancel out 2
Apply law of indices
---equivalent
Express as exponent
Apply law of indices
---- equivalent
Solve exponents
---- not equivalent
