Answer:

x=-5

Step-by-step explanation:

4-2(x+7)=3(x+5)

Distribute:

4-2*(x)-2*(7)=3*(x)3*(5)

Simplify

4-2x-14=3x+15

Simplify each side by combining like terms

-2x-10=3x+15

Add 10 to both sides

-2x-10+10=3x+15+10\\-2x=3x+25

Subtract 3x from both sides

-2x-3x=3x-3x+25\\-5x=25

Divide both sides by -5

\frac{-5x}{-5} =\frac{25}{-5} \\x=-5

Done

Find all prime numbers that differ by 17.

Those would be 2 and 19.

Since the difference is odd, one of the primes must be even. There is only one even prime, hence only one answer to your question.

Please look at image and tell me what the right answer is!!!<br><br> WILL REWARD BRAINIEST!!
Goryan [66]

Answer:

See below.

Step-by-step explanation:

Recall that the biggest angle will always be opposite from the biggest side.

IT is opposite from Angle S, which we can figure out to be 180-108-25=47.

SI is opposite from Angle T, which is 41.

ST is opposite from Angle I (the whole thing). Just from looking at it, we know that it is the biggest angle. If we want to figure it out, Angle I is 180-41-72+25=92.

The smallest side is SI, then IT, then ST.

The correct order is: SI, IT, and ST.
