Answer: none of these are right, the correct answer would be 7
Step-by-step explanation:
Count the squares in between each letter.
Point Q is 6 units from Point R
Point R is 7 units from Point T
Point T is 3 units from Point S
For the area, it is easiest to take the area of each of those shapes and then add them.
(3*7/2) + (6*7)
10.5 + 42 = 52.5 Square Units
2ab + a^3 + 5a^2b^2 - 2b^3
= a^3 - 2b^3 + 2ab + 5a^2b^2 (this is the expression in standard form)
Explanation:
Regardless of the number of factors, the product will be negative if an odd number of factors are negative.
In the example, 3 of the factors are negative. 3 is an odd number so the product will be negative.
-2*-3*-1*1 = -6
_____
Of course, the product will be zero if any factor is zero, regardless of the signs of any other factors.
$1,000/12 = 83.3 repeated
Each person will reserve about $83.
