6b + 5
Step-by-step explanation:
We begin by expounding the equation so as to remove the brackets;
2(a -3) + 4b - 2(a -b -3) + 5
2a – 6 + 4b - 2a + 2b + 6 + 5
Then we put the like terms together;
2a – 2a + 4b + 2b – 6 + 6 + 5
Now when the equation is simplified will look like this;
= 6b + 5

To check whether the statements are correct, we need to convert cm to mm.
surface area of a cube = 6 a²
294 cm² = 6 a²
294 cm² / 6 = a²
49 cm² = a²
√49 cm² = √a²
7cm = a
1 cm = 10 mm
7 cm = 70 mm
Surface area of a cube = 6a²
= 6 * (70mm)² = 6 * 4,900mm² = 29,400mm²
<span>B. The number representing the surface area would increase.
</span><span>E. The actual surface area would stay the same.</span>
He has 9 choices for the first role, and that leaves him 8 people to choose for the second so he has 9*8 = 72 choices for the first two roles; that leaves 7 possible choices for the third role so that gives him 9*8*7 choices or 504 different ways he can assign the roles. i think this is correct.
