Determine which situation(s) best describes operations with the numbers 4.58 and -0.145. select all situations that apply.

the product and quotient of the decimal numbers are both negative.
the product and quotient of the decimal numbers are both positive.
the sum of the decimal numbers is negative.
the sum of the decimal number is positive.
the difference of the decimal numbers is negative.
the difference of the decimal numbers is positive.

The product and the quotient of the decimal numbers are both negative
(because when multiplying/dividing, and ur signs are different, then ur answer will be negative)

The sum of the decimal numbers is positive
(because when adding, if the signs are different, u subtract and take the sign of the larger number)

The difference of the decimals is positive
(because ur subtracting a negative...4.58 - (- 0.145) = 4.58 + 0.145...and that equals a positive)

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
