Find the area of a square with a perimeter of 48 units

2 answers:

5 0

The equation for the perimeter of a square is P=4s (s=the length of each side)
So we can plug in the perimeter and solve for the side
48=4s
s=12 (divide both sides by 4)

The equation for the area of a square is A=s^2 or A=s*s
We can plug in the value for each side to find the area
A=12*12
A=144 units

Hope this helps!

3y-4x=3 find the rate of change for each function above Which function has the greatest rate of change?does any pair of function

pishuonlain [190]

Answer:

4/3

Step-by-step explanation:

Sounds as though this problem presented several rates of change, but you have shared only one: 3y - 4x = 3. If we take x to be the independent variable, then 3y = 4x + 3, and y = (4/3)x + 1. The rate of change of this function (the rate of change of y with respect to x) is therefore 4/3.

Please Help i will give the brainliest!

Dmitriy789 [7]

Answer:

<em>See below</em>

Step-by-step explanation:

In this example we are to consider the equation 2x - 5 = 4x + 12, and are asked to solve for x. Well let us take the first approach, a mathematical one;

$2x - 5 = 4x + 12,\\- 5 = 2x + 12,\\- 17 = 2x,\\\\x = - 17 / 2 = - 8.5\\\\Conclusion, x = - 8.5 / x = - 8 and 1 / 2$

Now consider the explanation, " talking over a phone to a friend. "

First you would subtract 2x on either side of the equation, canceling the 2x on one side, and subtracting 2x from 4x on the other, resulting in the simplified equation - 5 = 2x + 12. Subtracting 12 from either side we cancel the 12 on one side, and subtract - 12 and - 5 on the other. We now get - 17 = 2x. Dividing 2 on either side, x = - 8.5!

What is the solution to: <br> T/t-4=t+4/6

S_A_V [24]

$\frac{t}{t-4}= \frac{t+4}{6} \\ t \neq 4 \\ 6t= (t+4)(t-4) \\ 6t=t^2-16 \\ t^2-6t-16=0 \\ D=b^2-4ac=(-6)^2-4*1*(-16)=36+64=100 \\ t_{1,2}= \frac{-bб \sqrt{D} }{2a} \\ t_1= \frac{6-10}{2}=-2 \\ \ t_2= \frac{6+10}{2}=8$

Answer: t=-2, t=8

5. The cost of a notebook increased from $4.30 to $4.58, what is the percent increase?

KonstantinChe [14]

The answer is 6.5
Explanation : 1. Find out the increase number by subtracting 4.58 - 4.30 = 0.28 or 6.51%
2. Divide the increase number 0.28 by 4.30 and multiple by 100 which gives you 6.51162791 .
3. Get rid of all the numbers behind 5 and you can’t round it because 1 is too small. Which then gives you the answer 6.5 :) <3
