The length of a rectangle is 6 centimeters and its area is (6x + 18)square centimeters. Write an expression for the width.

1 answer:

5 0

Area=legnth times width
legnth=6
area=6x+18
subsitute
6x+18=6 times width

undistribute 6 from each term on left side
6(x+3)=6 times width
divide both sides by 6
x+3=width

Find the measure of the arc. Please help!

kolbaska11 [484]

Answer:

The value of mEFD = 214°

Step-by-step explanation:

Given that the measure of the degree of one of the central angles of an inner circle is 146°.

We know that sum of all central angles is 360°.

In other words, in our case

mEFD + 146° = 360°

Thus, we can determine the mEFD using the equation

mEFD + 146° = 360°

so subtracting 146° to both sides

mEFD + 146° - 146° = 360° - 146°

mEFD = 214°

Therefore, the value of mEFD = 214°

$18. \ \ \frac{-1}{x-9}- \frac{-2}{x+7}= \frac{-1(x+7)+2(x-9)}{(x-9)(x+7)}= \frac{-x-7+2x-18}{(x-9)(x+7)}= \frac{x-25}{(x-9)(x+7)}$

$\frac{2}{x}+ \frac{12}{x}=7 \\ \\ \frac{14}{x} =7 \\ \\ x= \frac{14}{7} \\ \\ x=2$
