1. Which equation can you use to find the value of x?

Mathematics
1 answer:
Alika [10]2 years ago
6 0

Answer:

It's a proportion.

2 is to x as 15 is to 9, or 2/x = 15/9.

Multiply the means and extremes

15x = 18

divide both sides by 15 to get x by itself.

x = 1.2

(w-w^2)^4=?<br>.......................​
Setler [38]

Answer:

w^8 - 4w^7 + 6w^6  - 4w^5 + w^4 .

Step-by-step explanation:

(w - w^2)^4

= w^4 ( 1 - w)^4

By the binomial theorem:

= w^4( 1  - 4w + 6w^2 - 4w^3 + w^4)

= w^4 - 4w^5 + 6w^6 - 4w^7 + w^8

=  w^8 - 4w^7 + 6w^6  - 4w^5 + w^4 ( Standard form).

Which one of the following formulas defines the area, A A , of a square in terms of its perimeter, p ?
pav-90 [236]
A square has 4 sides of equa length

the perimiter is 4 times the side, or P=4s where s=length of 1 side

the area is length times witdth, but since the length=width, area=s² where s is the length of one side

so express A=s² in terms of P when P=4s

solve for s first in P=4s
P=4s
divide both sides by 4
\frac{P}{4}=s

subsitute \frac{P}{4} for s in the other eqaution
A=s^2
A=(\frac{P}{4})^2
A=\frac{P^2}{16}



in terms of the perimiter, the area is A=\frac{P^2}{16}
