Answer: D. 12
Step-by-step explanation:
The first step here is to find all the possible selections and the number of options for each selection:
bread: 2 options (white or wheat)
meat: 3 options (beef, ham or turkey)
cheese: 2 options (swiss or cheddar)
The total number of combinations (of different possible sandwiches that Ray can order) is equal to the product between the numbers of options for each selection, so we have:
Combinations = 2*3*2 = 12
So the correct option is D.
<span>−1/8 x (2H + 4) + 1/2= −7/4
-1/4H - 1/2+ 1/2 = -7/4
-1/4H = -7/4
H = -7/4 * (-4/1)
H = 7

Answer:
14 units²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = 
bh ( b is the base and h the perpendicular height )
Here b = 7 and h = 4 , so
A = × 7 × 4 = × 28 = 14 units²
Basically, you are asking how many ways can 5 objects be chosen from 12 (the order is NOT important).
The formula for this is n! / [ r! * (n-r)! ]
12! / [5! * 7!] =
12*11*10*9*8*7! / (5! * 7!) =
12*11*10*9*8 / 5 * 4 * 3 * 2 =
11*9*8 =
792 different collections

2 (x - 4) = -2x + 3 + 4x
2x - 8 + 2x + 3
-8 = 3 so the statment is false for any value of x
