Answer:

x=20

Step-by-step explanation:

Since angle RTS is a right angle, we have three similar triangles.

Thus, \frac{x}{25} = \frac{16}{x}

Cross Products, x^2=400

Take the square root: x=20

Best explained/correct answer gets brainliest.
Nuetrik [128]
3, 15, 75, 375, and here's why:
Basically, it's asking you to take 3, and multiply it by five each time to get a pattern.

1: 3
2: 
3*5 = 15
3: 
15*5 = 75
4: 
75*5 = 375

Add these together: 
3 + 15 + 75 + 375 = 468

Your answer is "A)", 468.

Simplify 12√18-6√20-3√50-8√45
Alex_Xolod [135]

12√18-6√20-3√50-8√45

<em>*Break each radical up into the product of a radical of a perfect square and a second radical*</em>

12(√9*√2)-6(√4*√5)-3(√25*√2)-8(√9*√5)

<em>*Simplify the radicals*</em>

12(3√2)-6(2√5)-3(5√2)-8(3√5)

<em>*Distribute*</em>

36√2-12√5-15√2-24√5

<em>*Combine like terms</em>*

21√2-36√5

Hope this helps!!

Which equation does not represent a function? Why? A) y = x2; There are two outputs for each input. B) y2 = 4x; There are two ou
natita [175]

Answer:

B) y² = 4x; There are two outputs for each input

Step-by-step explanation:

For an equation to be called a function, the input values for x must only result in a single output for y.

Based on this definition if a function, the functions y = x², y = -x and y = x are all functions because for any value of x imputed in them, we can only get one equivalent value of y.

The only exception is the function y²= 4x

For this function, for any value of x, there will be more than one output for y. Take x = 1 for example

y² = 4(1)

y² = 4

y = ±√4

y = ±2

This shows that y = 2 and -2

Also if x = 4

y² = 4(4)

y² = 16

y = ±√16

y = ±4

y = 4 and -4

No matter the value of x imputed, the output value y will always be two (a positive and a negative value)

Hence, option B is correct.
