Answer: x = 2.36

Step-by-step explanation:

Graphic solution is attached.

approximate solution is 2.36 according to the graph

Verifying the solution as asked:

x + 2 = x³ - 2x - 4

2.36 + 2 = 2.36³ - 2*2.36 - 4

4.36 = 13.14 - 4.72 - 4

4.36 ≈ 4.42

If we round to 4.4 it's clearer that this is the right solution.

Step-by-step explanation: (I'm not gonna' do it all for you tho)

to convert from percent to fraction:

70% = $\frac{70}{100} =\frac{7}{10}$

to convert from fraction to percent:

$\frac{11}{20}=\frac{55}{100}$ = 55%

to convert from fraction to decimal:

$\frac{3}{25} =\frac{12}{100} =0.12$

to convert from decimal to fraction:

$1.25=\frac{125}{100} =1\frac{25}{100} =1\frac{1}{4}$

to convert from percent to decimal:

0.2% = $\frac{0.2}{100} =0.002$

to convert from decimal to percent:

$0.4= (0.4*100)$ % = 40%

With that, you can solve the rest on your own

Find the measures of an interior angle and an exterior angle of a regular hexagon. The measure of an interior angle is 120. The

Tom [10]

Answer:

see explanation

Step-by-step explanation:

Since a hexagon has 6 interior angles and the measure of one is 120°, then

sum of interior angles = 6 × 120° = 720°

exterior angle = 180° - interior angle = 180° - 120° = 60°
