Which expressions are equivalent to (4⋅a)⋅2 Drag and drop the equivalent expressions into the box. A. 4 x (a x 2) B. 4x2xax2 C 8

aksik [14]

(4*a)*2

lets give a a number: a = 3 so (4*3)*2 = 12*2 = 24

lets try the options:

A) 4 *(3*2) = 4*6 = 24 = the same

B) 4*2*3*2 = 8*3*2 = 24*2 = 48 = different

C) 8*3 = 24 = same

D) 4*2+3*2 = 8 +6 = 14 = different

E) 2*(4*3) = 2*12 = 24 = same

so A, C & E would be the equivalent.

$a_1=-8;\ a_2=-4;\ r=a_2:a_1\to r=-4:(-8)=\dfrac{1}{2};\ n=7\\\\S_n=\dfrac{a_1(1-r^n)}{1-r}\\\\subtitute:\\\\S_7=\dfrac{-8\left[1-\left(\dfrac{1}{2}\right)^7\right]}{1-\dfrac{1}{2}}=\dfrac{-8\left(1-\dfrac{1}{128}\right)}{\dfrac{1}{2}}\\\\=\dfrac{-8\cdot\dfrac{127}{128}}{\dfrac{1}{2}}=-\dfrac{127}{16}\cdot\dfrac{2}{1}=-\dfrac{127}{8}=-15\dfrac{7}{8}$
