Assuming 2x2 is 2 multiplied by 2, and not a variable..

1. Multiply 2 and 2.

4 - 2x +7

2. Add 7 to 4.

11 - 2x.

Since the answer can no longer be simplified, 11 - 2x is your final answer.

The value is 5.48 or 5 inches because the parallelograms have equal opposite sides, so therefore the opposite angles are equal too so the
sinx=5.6/10
x=34
then sin34=h/9.8
h=5 inches.

Answer:

$= 2x + (4 \times 36) - (4 \times x)$
$= 2x + 144 - 4x$
$= (2x - 4x) + 144$
$= - 2x + 144$
$= - 2( x - 72)$

Ira Lisetskai [31]

Answer:

3.9 units

Step-by-step explanation:

We are given that,

Time taken by each swing = 2.2 seconds

The pendulum formula is given by, $T = 2\pi \sqrt{\frac{L}{32}}$ , where T is the time taken and L is the length of the swing.

So, we have,

$2.2= 2\pi \sqrt{\frac{L}{32}}$

i.e. $\frac{2.2}{2\pi}=\sqrt{\frac{L}{32}}$

i.e. $(\frac{2.2}{2\pi})^{2}=\frac{L}{32}$

i.e. $L=32\times (\frac{2.2}{2\pi})^{2}$

i.e. $L=32\times \frac{4.84}{4 \pi^2}$

i.e. $L=32\times \frac{1.21}{\pi^2}$

i.e. $L=\frac{38.72}{9.87}$

i.e. L = 3.923 units

So, rounded to tenths, the length of the swing is 3.9 units.
