Answer:

x = 12 cm

Step-by-step explanation:

Based on the tangent and secant theorem,

8² = 4(4 + x)

Solve for x

64 = 16 + 4x

Subtract 16 from both sides

64 - 16 = 4x

48 = 4x

Divide both sides by 4

48/4 = 4x/4

12 = x

x = 12

Answer:

$\frac{(3-2a)}{a^2}$

Step-by-step explanation:

Given expression is,

$\frac{3}{a^2}- \frac{2}{a}$

First equalize the denominators of the fractions,

$\frac{3}{a^2}-\frac{2a}{a^2}$

Now combine the fraction as a single fraction,

$\frac{(3-2a)}{a^2}$

Since, we can not solve this fraction further, this will be simplified form of the given expression.

The fahrenheit and celsius scales are related by the equation F = 9/5C+32.

Ksivusya [100]

Step-by-step explanation:

by the equation u put down as

F=9/5C+32

since mexico is 81°f

81=9/5C+32

81-32=9/5C

49=9/5C

49*5=9C

245=9C

C=245/9

C=27.2°

to the nearest whole number

C=27°C
