He organizes them into groups of 5, because all 3 groups can be multiplied or divided by 5.
The correct answer is: [C]: " 5 " .

Explanation:

Given: " a + 1 <span>− 2 = 4 " ; Solve for "a" ;
4 + 2 = 6 ;
6 </span>− 1 = 5 ; → a = 5 ;
To check our work:
5 + 1 − 2 = ? 4 ?? ;
5 + 1 = 6 ;
6 − 2 = 4. Yes!
So the answer is: [C]: " 5 ".

Volume of a regular prism=height times area of base
area of base=5
height=1 and 1/2
volume=5 times 1 and 1/2
volume=5+5/2
volume=15/2 aka 7.5 ft^3
Answer:
0.8
Step-by-step explanation:
i just did it
It's the third answer. This is because since there is no middle term where both variables are combined, that would lead to the signs of the 2 factors to be different. However, that still leaves 2 answers, 3 and 2. If we were to square i, you would get -1. This is because √-1 is equal to i. i^2 would be -1. Since the sign in the unfactored expression is positive and not negative, that would mean that the i in the factoring turned it around. that leads us to believe that answer 3 is the correct answer.
