Answer:

hello : answer : a) 9 cm 2

Step-by-step explanation:

A square has a perimeter of 12 : p = 4×c.....c is the length

12 = 4c

c = 12/4

c = 3

the area A= c²

A= 3² = 9 cm 2

jonny [76]

Answer:

$\mathrm{Factor}\:4x^4-32x^3-60x^2:\quad 4x^2\left(x^2-8x-15\right)\\$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^{b+c}=a^ba^c\\x^3=xx^2\\x^4=x^2x^2\\=4x^2x^2-32xx^2-60x^2\\\mathrm{Rewrite\:}60\mathrm{\:as\:}4\cdot \:15\\\mathrm{Rewrite\:}32\mathrm{\:as\:}4\cdot \:8\\=4x^2x^2-4\cdot \:8xx^2-4\cdot \:15x^2\\\mathrm{Factor\:out\:common\:term\:}4x^2\\=4x^2\left(x^2-8x-15\right)$

Five added to 6 times a number is equal to 2 less than 8 times the number. What is the number?

Morgarella [4.7K]

30N=2-8N

Subtract 8N from 30N and you get 22N.

22N=2

Divide by 22 on both sides. You get N=2/22

So your answer is N=1/11
