Answer 1

Answer:

For this case, we must simplify the following expression:

$\sqrt [3] {\frac {4x} {5}}$

For this, we follow the steps below:

We rewrite the expression as:

$\frac {\sqrt [3] {4x}} {\sqrt [3] {5}}$

We multiply by:

$\frac {(\sqrt [3] {5}) ^ 2} {(\sqrt [3] {5}) ^ 2}\n\frac {\sqrt [3] {4x}} {\sqrt [3] {5}} * \frac {(\sqrt [3] {5}) ^ 2} {(\sqrt [3] {5}) ^ 2} =$

We have by definition of multiplication of powers of equal base that:

$a ^ m * a ^ n = a ^ {m + n}$

So:

$\n\frac {\sqrt [3] {4x} * (\sqrt [3] {5}) ^ 2} {\sqrt [3] {5}) ^ 3} =\n\frac {\sqrt [3] {4x} * (\sqrt [3] {5}) ^ 2} {5} =$

We know that:

$(\sqrt [3] {5}) ^ 2 = \sqrt [3] {5 ^ 2}$

So, we have:

$\frac {\sqrt [3] {4x} * \sqrt [3] {5 ^ 2}} {5} =\n\frac {\sqrt [3] {4x} * \sqrt [3] {25}} {5} =\n\frac {\sqrt [3] {100x}} {5}$

Of the 216 students on the playground three-eighths are wearing white shoes how many children on the playground are not wearing white shoes

Answers

If 3/8 ARE wearing white schoes
Then 5/8 AREN'T wearing white shoes
because

8/8 - 3/8 = 5/8
8/8 is the same as 1

Therefore,
5/8 x 216/1 = y
If this is mental maths then,

You can cancel the 216 by 8 because the denominator of 5/8 is 8 to make 27

Therefore, the answer is 135

First, you need to turn 3/8 in to a decimal. You can do that by dividing 3 by 8. You should get .375 now multiply that with 216. you should get 81. That means 81 kids are wearing white shoes. To find how many are not wearing white shoe, subtract 81 from 216. That gives you 135. 135 students are not wearing white shoes.

What is the area of the rectangle?

15 square units
30 square units
45 square units
54 square units

Answers

Answer:54

Step-by-step explanation: To find the area of a rectangle, we need to multiply its length by its width. In this case, we can use the coordinates of the given points to determine the length and width of the rectangle. The points given are (-5, 2), (4, 2), (-5, -4), and (4, -4). We can see that the length of the rectangle is the difference between the x-coordinates of two opposite points: 4 - (-5) = 9 units. Similarly, the width is the difference between the y-coordinates of two opposite points: 2 - (-4) = 6 units. To find the area, we multiply the length by the width: 9 units × 6 units = 54 square units. Therefore, the area of the rectangle is 54 square units.

To find the area of a rectangle, you multiply the length by the width. In this case, the length of the rectangle is the distance between -5 and 4 on the x-axis, which is 9 units. The width of the rectangle is the distance between -4 and 2 on the y-axis, which is 6 units. So, the area of the rectangle is 9 units multiplied by 6 units, which equals 54 square units.

Factors of the quadratic equation;

The quadratic formula is a formula in elementary algebra that provides the solution (s) to a quadratic equation.

The factors of the given equation are;

$\rm m^2 + 12m+36\n\nm^2+6m+6m+36\n\nm(m+6)+6(m+6)\n\n(m+6)(m+6)\n\n(m+6)^2$

Hence, the factors of the equation are $\rm (m+6)^2$ .

Answer: Choice A which is (m+6)^2

Explanation:

Think of two numbers that multiply to 36 and add to 12. Those two numbers are 6 and 6

6+6 = 12

6*6 = 36

So we can factor it into (m+6)(m+6). Use the FOIL rule to expand it out to get m^2+12m+36 back again.

The expression (m+6)(m+6) is the same as (m+6)^2
