Answer:

(-7)2 = -14

Step-by-step explanation:

The parenthesis basically mean "multiply". So, this is a simple equation meaning -7 x 2. And remember, anytime we multiply a positive by a negative, you get a negative. So, simply multiply 7 x 2 = 14 and add a negative sign to make the solution true. So, -7 x 2 or (-7)2 = -14

Hope this helps! If you have any additional questions, please don't hesitate to ask me or your teacher to be sure you master the subject. Also thank you for the generous points!! Stay safe and please mark brainliest!!

Why are decimals called decimals? ​
natta225 [31]

Answer:

Step-by-step explanation:

Decimal comes from the Latin word decimus, meaning tenth, from the root word decem, or 10. The decimal system, therefore, has 10 as its base and is sometimes called a base-10 system. Decimal can also specifically refer to a number in the decimal system.

22nd term: 28, 23, 18, 13,..
Verizon [17]

Answer:

The 22nd Term is -77.

Step-by-step explanation:

The pattern is -5.  If you subtract 5 from each starting number you'll get the following number.

Ex:  28 - 23 = 5

      23 - 18  = 5

       18 - 13  = 5

Subtract 5, 22 times and you will get -77.

I hope this was the most brainliest answer, thank you for letting me help you !
