Carol bought a bamboo plant that was 62/4 feet high. when she got it home she cut 44/6 feet off of it . how tall was the plant a

Evgesh-ka [11]

Simplifying the values

$$6 \frac{2}{4} =\frac{26}{4}$ and $$4 \frac{4}{6} = \frac{28}{6}$ , we get

$$\frac{11}{6}$ tall was the plant after she cut it down.

<h3>What is fraction rule?</h3>

Let, the values be a, b, and c, then we get

$\frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}$

Carol bought a bamboo plant that was $$6 \frac{2}{4}$ feet high. when she got it home she cut $$4 \frac{4}{6}$ feet off of it.

$$6 \frac{2}{4} =\frac{26}{4}$ and $$4 \frac{4}{6} = \frac{28}{6}$

The common denominator exists 24,

$$\frac{26}{4}-\frac{28}{6}$

the term $\frac{26}{4}=\frac{13}{2}$

$$=\frac{13}{2}-\frac{28}{6}$

Canceling the term $\frac{28}{6}= \frac{14}{3}$

$$=\frac{13}{2}-\frac{14}{3}$

Least Common Multiplier of 2, 3 = 6

Adjust Fractions based on the LCM

$$=\frac{39}{6}-\frac{28}{6}$

By applying the fraction rule we get

$\frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}$

$$=\frac{39-28}{6}$

Subtract the numbers, and we get

39 - 28 = 11

$$=\frac{11}{6}$

$$\frac{11}{6}$ tall was the plant after she cut it down

The correct answer is $$\frac{11}{6}.$

Hi ppl I rlly need help I’ve been off school and I rlly need to know the mean of 263 240 and 256 also I need to know the mean of

SSSSS [86.1K]

Answer:

So the mean of 263,240,256 is 253 and the mean of 12,13,17 is 14

Step-by-step explanation:

To get the mean of these numbers you add all three of them together then you divide them by the amount of numbers so you are going to add 263+240+256=759 then you divide by 3

$759 \div 3 = 253$

Write the polynomial as a<br> product of linear factors,<br> x^4-5x^2-36

Lerok [7]

9514 1404 393

Answer:

(x +3)(x -3)(x +2i)(x -2i)

Step-by-step explanation:

The factoring to quadratics makes use of the fact that -36 = (-9)(4).

x^4 -5x^2 -36

= x^4 -9x^2 +4x^2 -36

= x^2(x^2 -9) +4(x^2 -9)

= (x^2 +4)(x^2 -9)

The form for factoring the difference of squares comes into play here. Of course -4 = (2i)^2.

= (x^2 -(2i)^2)(x^2 -3^2)

= (x -2i)(x +2i)(x -3)(x +3) . . . factored to linear terms
