3. State if each statement is correct. If it is not correct, then fix the mistake.

olya-2409 [2.1K]

Answer:

All are incorrect

Step-by-step explanation:

Required

Determine which is correct or not

$(a)\ 2x * 2x = 4x$

This is incorrect because:

$2x * 2x = 2 * 2 * x*x$

$2x * 2x = 4x^2$ ---- fixed

$(b)\ 3x^3 * 3x^3 = 9x^9$

This is incorrect because:

$3x^3 * 3x^3 = 3 * 3 * x^3 * x^3$

$3x^3 * 3x^3 = 9x^(3+3)$

$3x^3 * 3x^3 = 9x^6$ ---- fixed

$(c)\ 4x(4x + 5) =8x + 5$

This is incorrect because:

$4x(4x + 5) =4x * 4x + 4x * 5$

$4x(4x + 5) =16x^2 + 20x$ ---- fixed

a circle has a circumstance of 20. it has an arc on length 4. what is the central angle of the arc in degrees?

erastovalidia [21]

Answer:

∠72°.

Step-by-step explanation:

If a circle has a circumference of 20 and an arc with a length of 4, we can simply set up a ratio to determine the angle of the arc in degrees:

$\frac{4}{20} = \frac{x}{360}$

Cross multiply:

$1440 = 20x\\$

Divide both sides by '20':

x = 72°.

Therefore, the measure of the central angle of the arc is ∠72°.
