The numbers such that when multiplied gives -140 and added gives -31
are, 4 and -35.
Here we have to find the numbers,
Which is when multiplied gives = - 140
And when they added give -31
Since we know that,
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Therefore,
Now to finding such number proceed :
1 and -140 is wrong because 1 + -140 = -139
-1 and 140 is wrong because -1 + 140 = 139
2 and -70 is wrong because 2 + -70 = -68
-2 and 70 is wrong because -2 + 70 = 68
4 and -35 is right because 4 + -35 = -31
Hence we can see that,
Such numbers are 4 and -35.

Answer is choice C) Inverse property of addition; a number and its inverse are added
The number is 0.3 and its additive inverse is -0.3, which add to 0. You can flip things around to say that the number is -0.3 and its additive inverse is 0.3 to add them to the same result of 0. The order of addition doesn't matter. It's like saying 2+3 = 5 and 3+2 = 5
Using trigonometric ratios, the length in inches of the given triangle is 22 inches.
Given a right angled triangle.
The length of the hypotenuse is also given.
We can find the length of "a" using the sine trigonometric ratio.
We know that,
Sine of any angle is defined as the ratio of the opposite side to the hypotenuse of a right angled triangle.
Using the sine function here for the angle 30°,
sin (30°) = opposite side / adjacent side
sin (30°) = a / 44
Or,
a / 44 = sin (30°)
We know that sin (30°) = 1/2.
So,
a / 44 = 1/2
Multiplying both sides by 44, we get,
a = 44 / 2
a = 22 inches
Hence the length is 22 inches.
