Answer:

A) -7/9

Step-by-step explanation:

-4(x + 4x) = 2(2 - x) + 10

-4x - 16x = 4 - 2x + 10

-4x - 16x + 2x - 4 - 14 = 0

-18x -14 = 0

-18x = 14

x = - 14/18

x = - 7/9

Use function notation to represent the area of a circle whose circumference is 103 cm

Nataly_w [17]

Circumference of the circle $=103$ cm

i.e., $C = 2 \pi r = 103$

i.e., $r = \frac{103}{2 \pi}$

Area of the circle is given by

$A = \pi r^2$

$A = \pi (\frac{103}{2 \pi})^2$

$A = \pi (\frac{10609}{4 \pi^2})$

$A =\frac{10609}{4 \pi}$

Therefore, the area of the circle is: $A =\frac{10609}{4 \pi}$ $cm^2$
