HELP! My teacher didn't teach half the material! How do I do this!?!?!?!

Mathematics
1 answer:
Sladkaya [172]3 years ago

Answer:

<h2>x=-0.3</h2>

Step-by-step explanation:

1-(-7.2x+3.5)=5+3(7.4x-1) first parenthesis

1+7.2x-3.5=5+22.2x-3  

7.2x-2.5=2+22.2x (x on one side and numbers on other)

22.2x-7.2x= -2-2.5

15x=4.5 divide by 15

x=-4.5/15

<h2>x=-0.3</h2>

What postulate can be used to prove the triangles are congruent?
Komok [63]
The HL Postulate

You know that the two hypotenuses are congruent and that the two triangles each contain a shared segment in the middle (so by the reflexive property they are congruent). You have two congruent hypotenuses and two congruent legs, so you can conclude congruency by HL.

If you found this helpful, please make this the brainliest answer! :)

Answer:

7^{12}

Step-by-step explanation:

When you divide two numbers that have exponents and have the same base, just subtract the exponents. In this case, 7 is the base of both the dividend and the divisor. So, simply subtract 14 - 2 to get 12. The final answer is 7^{12}.
