I tried something similar to the notation of (x+2)^7, etc, did not get close at all, how would this be solved?
k0ka [10]

24 = 3 \cdot 2^3

96=3\cdot 2^5

384=3\cdot2^7

hence it is a geometric progression, with a multiplied constant 3

Sum of G.P. of n terms S_n = a\dfrac{r^n-1}{r-1}\quad \text{where } r \text{ is the common ratio and } a \text{ is the first term}

and r=-2^2=-4

Note that the constant should be separated, so

a= -8 [\tex]after plugging the values, you'll get the answer [tex] -26216 \times 3

which option C

Which problem could be solved with the expression 5 x ( 2 + 4 ) ÷ 6 ?
Pie

Answer:

1

Step-by-step explanation:

This is the only problem that could be answered with this equation, because you would add the bracelets he made (2+4) then times that number by the days he made them, 5, then divide by the number of groups, 6. Which equals 5 x ( 2 + 4 ) divided by 6.

I hope this helps!

10 minutes for 480 copies. Divide 480 by 10 and get 48 copies per minute. If you divide 720 by 48 you get 15, so it takes 15 minutes to make 720 copies.
