<span>General rule for adding numbers
Two integers with the same signs
=> Once 2 integers has the same sign, then add.
For example
5 + 3 = 8 ( 5 and 3 are both positive numbers)
-5 + (-3) = -8 (5 and 3 are both negative number, thus we added the 2 numbers)

Two integers with different signs
=> When 2 integers has different sign, then do subtraction
For example
-5 + 3  (5 and 3 has different signs)
- 5 + 3 = 2

Two integers that vary in sign
=> When 2 integers vary in sign, then it will depend on the operator
For example
5 + (-3) (5 and 3 has different signs, but the process will vary with the operator and number sign)
When positive and negative = negative
5 – 3 = 2

Volume of the prism = 75 cubic feet

Solution:

The image given is a rectangular prism (or) a cuboid.

Area of base = l × b = 25 square feet

Height of the prism = 3 feet

Volume of the prism = l × b × h

                                  = (l × b) × h

                                  = 25 × 3

                                  = 75 cubic feet

Volume of the prism = 75 cubic feet

Hence, the volume of the prism is 75 cubic feet.

Which graph represents the inverse sine function?
hichkok12 [17]
Answer: A.
The inverse sine function is written as sin−1(x) or arcsin(x). Inverse functions swap x- and y-values, so the range of inverse sine is − π/2 to π/2 and the domain is −1 to 1. When evaluating problems, use identities or start from the inside function.

How do I know when I need to use SSS or SAS in geometry? I'm having a lot of trouble understanding the difference and when to us
Pavel [41]
SSS = Side-Side-Side
If three sides of one triangle are congruent to three sides of another triangle then the triangles are congruent.


SAS  = Side-Angle-Side
If two sides and the included angle are equal to the corresponding parts of another triangle then the triangles are congruent.'
The angle must be formed by the two pairs of congruent, corresponding sides of the triangles. If the angles are not formed by the two sides that are congruent and corresponding to the other triangle's parts then you cannot use the SAS postulate.

you will notice that the main difference between the two postulates is that the SAS consists of an angle and the SSS does not.

hope this helps :)
