Answer:

\frac{9x^6}{4}-\frac{3x^5}{2}+\frac{x^4}{4}

Step-by-step explanation:

We want to simplify:

(6x-2)^2(0.5x)^4

We expand to get:

(36x^2-24x+4)*\frac{x^4}{16}

We expand further to get:

\frac{9x^6}{4}-\frac{3x^5}{2}+\frac{x^4}{4}

Ethan is 11 inches shorter than 3 times his little sister
PtichkaEL [24]

Answer:

30"

Step-by-step explanation:

We know:

E = 3*s - 11

E = 79"

Setting them both equal:

79 = 3s - 11

add 11 to both sides

79 + 11 = 3s - 11 + 11

Simplify

90 = 3s

divide both sides by 3

90 / 3 = 3s / 3

Simplify

s = 30"

60^2=48(48+x) and

3600 = 2304 + 48x and

1296 = 48x so

x = 27
