Answer:
27a^3b^8+8a^9b^12 (D)
Step-by-step explanation:
We are to determine which of the expression above in the options satisfy sum of a cube.
For an expression to considered sum of a cube, it must meet two conditions:
1) the expression would have same sign. It is mostly positive. If both are negative, the negative sign could be factored out.
2) Each of the term in the expression must be a cube. That is, each term must be the result of multiplying the same expression three times.
Let's check out the expressions in the options:
a) -27a^3b^6+8a^9b^12
The two terms in the expression have opposite signs
b) -9ab^6 +9610
The two terms in the expression havd opposite signs
c) 9ab^6 + 8a^12
The two terms in the expression have same signs. But 9ab^6 isn't a cube as we can't multiply a tern 3times to derive it, but 8a^12 is a cube.
d)27a^3b^8+8a^9b^12
The two terms in the expression have same signs (positive). 27a^3b^8 is a cube, 8a^9b^12 is also a cube
27a³b^8 = 3ab² × 3ab² × 3ab²
8a^9b^12 = 2a³b⁴ × 2a³b⁴ ×2a³b⁴
From the options above 27a^3b^8+8a^9b^12 is sum of a cube
Answer:
Quinn did not make a mistake. This is because everything she did is correct and also if we calculate the expression without doing anything she did, we see that she has the right answer.
75% means 75 per cent, or per hundred.
"Per cent" means "per hundred" or "0.01".
This means that 75% is 0.75 in decimal form.
75% as a fraction means 75 per hundred.
Keep in mind that "per" means to divide.
So, let's translate this into parenthesis.
75 (75) per (/) hundred (100).
Rewrite with only the parenthesis.
75 / 100.
This is 75% in fraction form, but isn't simplified. We can divide both numbers by 25.
75 / 25 = 3
100 / 25 = 4
Your simplified fraction is 3/4.
I hope this helps!
