Answer:

Step-by-step explanation:

Hello!

(a+b)(a+b)(a+b)

(a+b)(a+b) = a²+2ab + b²

(a²+2ab + b²) (a+b)=

a³ + a²b +  2a²b + 2ab² + ab² + b³ =

a³ + b³ +  2a²b + 2ab² + ab²  + a²b

laiz [17]

Answer:

C.  It is not possible to split the pistachios into 40 packages. It would be possible if there were a total of 4,280 pistachios

Step-by-step explanation:

Given

Pistachios = 4315

Packages = 40

Required

Determine if it's possible to divide into 40 packages

First, we need to divide the Pistachios by the number of packages.

Batches = 4315/40

Batches = 107.875

Because, we have a decimal; then it's impossible

However,

it'd be possible if

Pistachios = 4280

because:

4280/40 = 107

Alchen [17]

Answer:

The measure of the labeled angles is 135°

Step-by-step explanation:

we know that

if  a || b

then

(3x-27)\°=(2x+27)\° -----> by alternate exterior angles

Solve for x

3x-2x=27+27

x=54

Find the measure of the labeled angles

(3(54)-27)\°=135\°
