Answer:

30

Step-by-step explanation:

75% can also be written as 3/4. 3/4 can also be written as 30/40, or 30 out of 40, which in this case, means 30 out of 40 kids.

Perform each indicated operation
MissTica

Answer: \frac{x+6}{x-4}

Step-by-step explanation:

First you need know some general formuals of factorization such as

x^3+y^3=(x+y)(x^2-xy+y^2) so you have x^3+64=X^3+4^3=(x+4)(x^2-4x+4^2)

And, x^2-y^2=(x-y)(x+y) so you have 2x^2-32=2(x^2-16)=2(x^2-4^2)=2(x+4)(x-4)

If you use them, then you can modify your equations such as

\frac{x^3+64}{2x^2-32} ÷ \frac{x^2-4x+16}{2x+12} = \frac{(x+4)(x^2-4x+4^2)}{2(x+4)(x-4)} ÷ \frac{x^2-4x+16}{2(x+6)}  =  \frac{(x+4)(x^2-4x+4^2)}{2(x+4)(x-4)} . \frac{2(x+6)}{{x^2-4x+16}} = \frac{1}{x-4}.\frac{x+6}{1}=\frac{x+6}{x-4}

The measures of two sides of a triangle are 4in and 13in. Find all possible values that the third side of this triangle can be?
ElenaW [278]

Answer:

9 < x < 17 is the possible length of the third side of a triangle.

Step-by-step explanation:

The Triangle Inequality theorem defines that if we are given two sides of a triangle, the sum of any two given sides of a triangle must be greater than the measure of the 3rd side.

Given the two sides of the triangle

  • 4 in
  • 13 in

Let 'x' be the length of 3rd size.

According to the Triangle Inequality theorem,

The difference of two sides < x < The sum of two sides

13 - 4 < x < 13+4

9 < x < 17

Therefore, 9 < x < 17 is the possible length of the third side of a triangle.

andreyandreev [35.5K]
√4 + √16 = 2 + 4 = 6   <--- rational
√5 + √36 = √5 + 6   <--- irrational 
√9 + √24 = 3 + √24   <--- irrational
2 * √4 = 2 * 2 = 4   <--- rational 
√49 * √81 = 7 * 9 = 63   <---rational
3√12 = 3√(4 * 3) = (3 * 2)√3 = 6√3    <---irrational

Hope this helps ^-^
