Answer:

The area of the carpet which is square in shape is 81 $inches^2$

Step-by-step explanation:

Given:

side of the carpet square = 9 inches

To Find:

area of the carpet square = ?

Solution:

The area of the carpet = area of the square

we know that the area of the square is

=> side X side

Substituting the side of the square, we get

=> 9 X 9

=> 81 $inches^2$

18. Find the value of x that makes the equation true.

IgorC [24]

Step-by-step explanation:

✧ $\large{ \tt{ \: \frac{1}{2} x + 2 = \frac{3}{2} x - 6}}$

We need to get rid of the fractions. Notice that there are 4 terms in the equation. Multiply both sides of the equation by 2 to get rid of the fractions. Multiply by 2 because 2 is the denominator.

⤑ $\large{ \tt{2( \frac{1}{2} x + 2) = 2( \frac{3}{2} x - 6)}}$

⤑ $\large{ \tt{x + 4 = 3x - 12}}$

Subtract 4 from both sides in order to isolate the variable on the left.

⤑ $\large{ \tt{x + 4 - 4 = 3x - 12 - 4}}$

⤑ $\large{ \tt{x = 3x - 16}}$

Move 3x to left hand side and change it's sign

⤑ $\large {\tt{x - 3x = - 16}}$

Subtract 3x from 1x

⤑ $\large{ \tt{ - 2x = - 16}}$

Divide both sides of the equation by -2

⤑ $\large{ \tt{ \frac{ - 2x}{ - 2} = \frac{ - 16}{ - 2}}}$

⤑ $\large{ \tt{x = 8}}$

$\boxed{ \boxed{ \underline{ \tt{Our \: Final \: Answer : \boxed{ \underline{ \tt{x = 8}}}}}}}$

Solve, correct people get brainliest

Zigmanuir [339]

Solution:

Note that:

5t - 8 + 68 = 180

Use the equation above to solve for t.

5t - 8 + 68 = 180
=> 5t + 60 = 180
=> 5t = 180 - 60
=> 5t = 120
=> t = 120/5 = 24

The value of t is 24.

Please help me! The i is an imaginary number (9+4i)^2

beks73 [17]

Answer: 2500

Explanation: I turned the I into a 1 and it turned into a 41 so I added 9+41 which is 50. Then I multiplied 50 by 50 because of the ^2 which gave me 2500. I’m assuming that you can put whatever number as a replacement for the I. I’m sorry if this answer isn’t right.

4th term of (4x-y)^9

Neko [114]

Now, let's do the same as we did for the previous one here.

$\bf (4x-y)^9\implies 
\begin{array}{llll}
term&coefficient&value\\
-----&-----&-----\\
1&+1&(4x)^9(-y)^0\\
2&+9&(4x)^8(-y)^1\\
3&+36&(4x)^7(-y)^2\\
4&+84&(4x)^6(-y)^3
\end{array}$

notice again, how did we get 84 for the 4th element's coefficient? well 36 * 7 / 3. and so on. And you can just expand it from there.
