If a square has the perimeter of 15.2 centimeters, what are 2 equations that can determine the perimeter of the square?

astraxan [27]

Answer:

1) $P=4s$

2) $P=4\sqrt{A}$

see the explanation

Step-by-step explanation:

we know that

The perimeter of the square is equal to

$P=4s$

where

s is the length side of the square

we have

$P=15,2\ cm$

substitute

$15.2=4s$

solve for s

$s=15.2/4=3.8\ cm$

The area of a square is equal to

$A=s^2$

substitute

$A=3.8^2=14.44\ cm^2$

we have that

$s=\sqrt{A}$

therefore

2 equations that can determine the perimeter of the square are

1) $P=4s$ ----> $P=4(3.8)=15.2\ cm$

2) $P=4\sqrt{A}$ ----> $P=4\sqrt{14.44}=15.2\ cm$

Work out m and c for the line: 3 y + 6 x = − 3

Usimov [2.4K]

Answer:

m is -2 and c is -1

Step-by-step explanation:

• Let's first phrase out the general equation of a line

${ \rm{y = mx + c}}$

m is the slope
c is the y-intercept

[ remember that a general line equation must be in slope - intercept form as shown above ]

• from our question, we are given the equation;

${ \rm{3y + 6x = - 3}}$

• let's make y the subject in order to make the equation in slope - intercept format.

→ remember to apply "subject making knowledge"

${ \rm{3y = - 3 - 6x}} \\ \\ { \rm{3y = - 6x - 3}} \\ \\ { \rm{ \frac{3y}{3} = \frac{ - 6x}{3} - \frac{3}{3} }} \\ \\ { \boxed{ \rm{y = - 2x - 1}}}$

• The above boxed equation is now a general equation. Let's extract out slope, m and y-intercept, c

${ \rm{m \: \dashrightarrow \: - 2}} \\ \\ { \rm{c \: \dashrightarrow \: - 1}}$
