Hi there.

Okay, thanks Alan.

w² + 14w + 49 is correct.

.

Oops. You're right! Better fix it.

(Also looked it over, it is either w² + 14w + 49 or 14w³ + 49)

Your first two lines are correct Obscure, but you go wrong after that (e.g. 7*7 = 49 not 14).

<WXZ  = <YXZ  [second answer ]

(w+7)² = (w+7)(w+7)

{Use distributive property}: w(w + 7) + 7(w + 7)

Multiply: (w² + 7w) + (7w + 49)

Add Common Factors: (7w + 7w = 14w)

Simplify/Answer: w² + 14w + 49

{nl}(Why does it keep saying this when I edit?)

Like so:

\(\frac{8*5^{17}+11*5^{18}}{5^{18}* 63}\rightarrow \frac{5^{17}(8+11*5)}{5^{18}* 63}\rightarrow \frac{8+11*5}{5*63}\rightarrow\frac{1}{5}\)

2x + 3x = 2 * x + 3 * x = 5 * x = 5x

#x basically means # * x, because it is multiplying.
