7 0

Answer:

(4k^2+7)(7k+6)

Step-by-step explanation:

1. group the first two terms (28k^3-24k^2). The greatest common factor is 4k^2. If you factor that out you get 4k^2(7k-6)

2.When you group the last two terms (49k-42). you can factor out a 7.

7(7k-6).

3. There is a (7k-6) in both sections so you can combine all the terms.

4k^2(7k-6) 7(7k-6) becomes (4k^2)(7k-6)

What is the measure of an interior angle of a regular hexagon?

maria [59]

For a polygon,
the Sum of Interior Angles = (Number of Sides -2) • 180 degrees
hexagon = 6 sides so
(6 -2) * 180
all angles sum to 720 So each angle = (720/6) = 120 degrees

If AC=18x-7,find the x. Round to the nearest hundredth if necessary AB=7x+29 BC=30

Margaret [11]

Answer:

$x=6$

Step-by-step explanation:

AC = AB + BC

$18x-7=(7x+29)+30$

$18x-7=7x+29+30$

$18x-7=7x+59$

Add 7 to both sides:

$18x-7+7=7x+59+7$

$18x=7x+66$

Subtract 7x from both sides:

$11x=66$

Divide both sides by 11:

$\frac{11x}{11}=\frac{66}{11}$

$x=6$
