Answer:
x = ± 10
Step-by-step explanation:
Given
x² - 100 = 0 ( add 100 to both sides )
x² = 100 ( take the square root of both sides )
x = ± 
← note plus or minus, hence
x = ± 10
Answer:
48,000
Step-by-step explanation:
320,000÷100=3200
1/100=3200
×15=48,000
therefore 15/100=48,000
Hello there!
The expression:48x+ 56xy
We know we can't add them together since 56 is being multiplied by y. We aren't going to combine 48x and 56xy. They will remain separate terms.
We know that "C" and "D" are not the answers.
However, we can check the following expressions to see if they match the given expression.
8x(6+7y)= 8x*6= 48x 8x*7y= 56xy <=== "A" is correct
"A" is the correct answer.
I hope this helps!
