Answer:
a = 5r² and b = r²s
Step-by-step explanation:
a3 - b3 = (a - b)(a + ab + b2)
Expressing 125q^6-r^6s^3 as a difference of 2 cubes
125q^6-r^6s^3
= 5³(r²)³ - (r³)²s³
= (5r²)³ - (r²s)³
Comparing with a³ - b³
a = 5r² and b = r²s
Hence the value of a is 5r² and b is r²s
Answer:
The variable titled "the number" is A: 12.
Step-by-step explanation:
The problem is 8 * (x - 6) = 4 * x
Try the first number as x and rewrite the expression.
8 * (12 - 6) = 4 * 12
Following PEMDAS (the Order of Operations), you need to solve the problem inside the parenthesis.
12 - 6 = 6
Rewrite the problem.
8 * 6 = 4 * 12
8 times 6 is 48.
4 times 12 is 48.
The variable in the expression 8 * (x - 6) = 4 * x is 12.
The answer is:
x=-8
Because:
If you pick a number(-8) to fill in the equation written below
5x+20+5x=5x-20
After applying the -8 to x you get
-40+20-40=-40-20
When you simply the both sides you get
-60=-60
And that’s right -60 is equal to -60!
(10^2 +10^2)^.5 = 10*(sqrt2)
