Answer:
m
Step-by-step explanation:
Triangular prism
length of slanted side:
sqrt(3^2 + 4^2) = 5
SA = 2(1/2)(8)(3) + 8(12) + 2(5)(12) =240
V = (1/2)(8)(3)(12) = 144
cuboid
SA = 2(7x6) + 2(7x5) + 2(6x5) = 214
V = 7x6x5 = 210
The answer is 266 but estimated is 260
Answer:
Step-by-step explanation:
I'm going to assume that the problem is -23x -214 = 274
And in that case...
1. First isolate the x-value by adding 214 to both sides of the equation:
-23x = 488
2. Then, divide both sides by -23 to truly get x alone:
x =
or -21.22
Number of red cards including 2 red queens = 26
Number of black queens = 2
Therefore, number of red cards including 2 red queens and 2 black queens = 26 + 2 = 28
Number of cards neither a red card nor a queen = 52 - 28 = 24
