Answer:

You didn't include anything to find X and Y, but I can help you find it in the future.

Step-by-step explanation:

In order to find X or Y in an equation, do the opposite with the last two numbers.

Example:

2x+1 = 5

You see that we are adding here.

So, we must do the opposite with 1 and 5.

1-5=4

That means that 2x will equal four, which means that x must be 2.

2x2+1=5 This is true, because 2x2=4 + 1 = 5.

The width of a rectangle measures (7d + 8f) centimeters, and its

Andre45 [30]

The expression which represents the perimeter, in centimeters, of the rectangle is; (18d +10f) centimetres.

<h3>Perimeter of a rectangle</h3>

Since the perimeter of a rectangle is given by the formula;

Perimeter, P = 2l + 2w.

In essence, Perimeter, P = 2(2d – 3f) + 2(7d + 8f)

P = 4d -6f + 14d +16f

P = 18d +10f.

Ultimately, the perimeter of the rectangle is; (18d +10f) centimetres.

Check the picture below.

$\bf \textit{volume of a pyramid}\\\\
V=\cfrac{1}{3}Bh\qquad 
\begin{cases}
B=area~of\\
\qquad its~base\\
h=height\\
------\\
B=\stackrel{14\times 14}{196}\\
h=24
\end{cases}\implies V=\cfrac{1}{3}(196)(24)$

Hello there can anyone solve this plz (chart is attached):

stich3 [128]

Answer:

$h^\prime(1)=14$

Step-by-step explanation:

We have the function:

$h(x)=f[f(x)]$

And we want to find:

$h^\prime(1)$

So, we will differentiate function <em>h</em>. By the chain rule, this yields:

$h^\prime(x)=f^\prime[f(x)]\cdot f^\prime(x)$

Then it follows that:

$h^\prime(1)=f^\prime[f(1)]\cdot f^\prime(1)$

Using the table, we acquire:

$h^\prime(1)=f^\prime(3)\cdot2$

And using the table again, we acquire:

$h^\prime(1)=7\cdot 2$

Evaluate. Hence:

$h^\prime(1)=14$
