Answer:x=-4

Step-by-step explanation:

move 5x to the other side by cancelling it out with -5x

that causes it to be 6-6x=30

move 6 to other side by cancelling out with -6

causes it to be -6x=24

divide by -6 to get x alone

x=24/-6

answer is -4 when reduced

A triangle has one leg that measures 14 feet and the hypotenuse is 50 feet. What is the length of the other leg?
Aliun [14]
Ok so we are using the Pythagorean theorem so were gonna do A^2 + B^2 = C^2

It don't say which leg we have so you can use either a or b.
Which would get us 14^2 + B^2 = 50^2
14*14 =196 , 50 *50 =2500
Then we have to  subtract the two.
So 2500 - 196 = 2,304
Then you take the take the square root of that answer and you have your other leg. 
The square root of 2,304 is 48
So the missing leg = 48

What is a formula for the nth term of the given sequence?<br> 36, 24, 16...
SpyIntel [72]

Answer:

The formula to find the nth term of the given sequence is 54 · \frac{2}{3} ^{n}

Step-by-step explanation:

The formula for nth term of an geometric progression is :

a_{n} = \frac{a_{1}(r^{n})}{r}

In this example, we have a_{1} = 36 (the first term in the sequence) and

r = \frac{2}{3} (the rate in which the sequence is changing).

Knowing what the values for r and a_{1} are, now we can solve.

a_{n} = \frac{a_{1}(r^{n})}{r} = \frac{36 (\frac{2}{3} ^{n}) }{\frac{2}{3} } = 54 · \frac{2}{3} ^{n}

Therefore, the formula to find the nth term of the given sequence is

54 · \frac{2}{3} ^{n}
