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

Evaluate this piecewise function
ohaa [14]

Answer:

f(-2) = 2 and f(0) = 0.

Step-by-step explanation:

The piece wise function is given by, f(x) = x³ for x ≠ - 2 and f(x) = |x| for x = - 2.

Now, as defined above at x = -2, f(x) = |- 2| = 2

So, f(-2) = 2

Again, at x = 0, f(x) = x³ = (0)³ = 0.

So, f(0) = 0.

Hence, f(-2) = 2 and f(0) = 0. (Answer)

(x) + (x + 1) + (x + 2) = 75
Anvisha [2.4K]

Answer: x=24

Step-by-step explanation:

step 1: remove parenthesis  x+x+1+x+2=75

step 2: collect like terms 3x+3=75

step 3: move the constant to the right side of equation 3x=75-3

step 4: subtract 3x=72

step 5: divide both sides by three to get x by itself x=24
