Since you know that a square has 4 equal sides then you know the small squares are 4cm on all sides and the big squares are 9cm on all sides.

If 2 and a partial sm sq are next to a 9cm sq then knowing 4*2=8 you can figure out that the other square is split as 1cm and 3cm(1+3=4), 3cm of which is lined up with the width (4cm)of another sm sq which would equal 7cm, these 2 sm sqs line up with the unknown sq whose sides would in turn also be 7cm.

A=l*w, 7*7=49

Answer:Area=49cm^2

If f(x)=4^x, find f(4)
lina2011 [118]

Answer:

\huge\boxed{f(4) = 256}

Step-by-step explanation:

<u>Given function is:</u>

f(x) = 4^x

Put x = 4

So,

f(4) = 4^4\\\\f(4) = 256\\\\\rule[225]{225}{2}

Need help also if you can can you do it step-by-step explanation please thank you 3(c + 8) = 28<br>​
skelet666 [1.2K]

Answer:

c = 4/3

Step-by-step explanation:

3(c + 8) = 28

Since we have paranthesis, first use the dsitributive property [multiply 3 by c and 8]

3(c + 8) = 28

3c + 24 = 28

To find the value of c, you must have c alone on one side, so subtract 24 from both sides

3c + 24 = 28

3c = 4

Now, divide by 3 to both sides to get your answer

3c = 4

c = 4/3

Therefore, the answer is 4/3!

I hope this helps! :)

What is the quantum concept of the terminal notion of pi
GrogVix [38]
By applying the variational approach and then comparing the result to the exact solution, we can calculate the error in the approximation. That is the main and major use of Terminal notation of pi.

π/2 = [tex] \lim_{n \to \infty} π  (2j)(2j) / (2j-1)(2j+1)

Here, by this expression, we set the limits, and get the approximate error in the experiment.

Hope this helps!

Solve each system using the substitution method 6x-y=-4 and 2x+2y=15
Fynjy0 [20]
Convert 6x - y = -4 into y = mx + b
Y - 4 = 6x
Y = 6x + 4
Substitute that into second equation
2x + 2(6x + 4) = 15
2x + 12x + 8 = 15
14x = 7
X = 1/2
6(1/2) - y = -4
3 - y = -4
-y = -7, y = 7
Final answer: x = 1/2, y = 7
