The options have not been given but three correct alternatives have been presented as the solution.

Answer:

3(c-2)(c-3) or3(c^2-5c+6) or 3c^2 - 15c + 18

Step-by-step explanation:

\dfrac{c^2-4}{c+3}\div\dfrac{c+2}{3(c^2-9)}

Applying the rule a^2 - b^2 = (a+b)(a-b) to the numerator of the first term and the denominator of the second term,

\dfrac{c^2-2^2}{c+3}\div\dfrac{c+2}{3(c^2-3^2)}

\dfrac{(c+2)(c-2)}{c+3}\div\dfrac{c+2}{3(c+3)(c-3)}

By changing ÷ to ×, we invert the second term

\dfrac{(c+2)(c-2)}{c+3}\times\dfrac{3(c+3)(c-3)}{c+2}

(c-2)\times3(c-3)

3(c-2)(c-3) = 3(c^2-5c+6) = 3c^2 - 15c + 18

CAN SOMEONE HELP ME UNDERSTAND THIS PLEASE
ICE Princess25 [194]

YEAH OFC SHAWTY!

  • so for A its -4^11 because if the powers have the same base and they are being multiplied you add the powers
  • For B its the same idea, they have the same base, and are being multiplied so you add the powers- 13^9
  • For C its similar, you have the same base, but since its Dividing, you subtract the powers. So, 9^5
  • for D you pretend like the denominator has a power of 1 and subtract. So its -24^5-24^1 which hopefully puts it into perspective of being -24^4 becuase we subtracted the powers

I cant do 2 right now, but i will in a minute

<u>And for 3 his mistake is that they arent the same bases so he cant add the powers, he should have converted them to the same base first. </u>

What is the LCD of 2/5 and 4/11
scoundrel [369]
To find the lowest common denominator you need to know the factors of 5 and 11.
So make two lists:
5, 10, 15, 20, 25, 30, and so on.
11, 22, 33, 44, 55, 66, and so on.
Keep doing that until you find the lowest common number in the lists. The LCD will be 55.

A company sells a mix of peanuts and cashews. For every 3 ounces of peanuts, there are 2 ounces of cashews. A batch has 60 ounce
shtirl [24]

Answer:

Proportion states that the two ratios or fraction are equal.

As per the given statement: For every 3 ounces of peanuts, there are 2 ounces of cashews. A batch has 60 ounces of peanuts.

Let x be the ounces of cashew will a batch have.

then by definition of proportion, we have;

\frac{3}{2} = \frac{60}{x}

By cross multiply we have;

3x = 120

Divide by 3 on both sides we get;

x = 40

therefore, 40 ounces of cashews will a batch have for every 60 ounces of peanuts.
