If AC = 52, AB = 8x + 8, and BC = 2x + 4, then the length BC is

Reil [10]2 years ago

Answer:

Step-by-step explanation:

AC = AB + BC

Since we know what each variable equals, we can write out the equation as shown:

52 = 8X + 8 + 2X + 4

Combining like terms:

52 = 10X + 12

Subtract 12 from both sides:

40 = 10X

Divide by 10:

X = 4

Now that we know X, we can figure out BC

BC = 2(4) + 4

BC = 8 + 4

BC = 12

Therefore BC is 12.

A roof drops 6 feet for every 3 feet forword,determine the slope of the roof the slope can be positive or negative

dalvyx [7]

Answer:

The slope is -2

Step-by-step explanation:

Since the roof is decreasing in height as it goes forward, I know that the slope must be negative. The equation to find the slope is rise/run. The vertical change, or the rise, is -6 feet, so that value goes on top of the fraction. The horizontal value, or the run, is 3 feet so that goes on the bottom of the fraction.

Now our fraction is $\frac{-6}{3}$

If you simplify that fraction, you'll get -2.
