Since E is the midpoint, DE and EF are the same length.
Set the equation DE and EF equal to each other and solve for x.
2x + 4 = 3x - 1
x = 5
Then plug in 5 to find the length.
DE = 2(5) + 4 = 14
EF = 3(5) - 1 = 14
DF = DE + EF = 28

Your job is 7.5 miles from home. One option is to take the back roads to work. That route is calculated for driving at an averag
fomenos

Step-by-step explanation:

So if you are 7 and a half miles away, and you drive 30 miles per hour, you need to take 7.5 and divide it by it by 30 and you get 0.25, you then need to find what is a quarter (0.25) of 60 minutes, and you will find that it is 15 minutes.

So:

Answer:

The route will take 15 minutes to get to work taking the back roads.

Hope this helps!

Given: Circle O,
Lunna [17]
In A Circle:
If AB || CD ⇒ BC = AD = 16°
AB + BC + CD + AD = 360°
AB + CD + 2BC = 360°
48° + CD + (2*16°) = 360°
CD = 360° - 48° - 32°
CD = 280°

1/4b^2+ 4bc + 16c?<br> Answer?
Charra [1.4K]

Answer:

1/4b^2+ 4bc + 16c?=4

Step-by-step explanation:

STEP

1

:

           1

Simplify   —

           4

Equation at the end of step

1

:

   1                  

 ((— • b2) +  4bc) +  16c

   4                  

STEP

2

:

Equation at the end of step 2

  b2            

 (—— +  4bc) +  16c

  4            

STEP

3

:

Rewriting the whole as an Equivalent Fraction

3.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  4  as the denominator :

          4bc     4bc • 4

   4bc =  ———  =  ———————

           1         4  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

3.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

b2 + 4bc • 4     b2 + 16bc

————————————  =  —————————

     4               4    

Equation at the end of step

3

:

 (b2 + 16bc)    

 ——————————— +  16c

      4        

STEP

4

:

Rewriting the whole as an Equivalent Fraction

4.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  4  as the denominator :

          16c     16c • 4

   16c =  ———  =  ———————

           1         4  

STEP

5

:

Pulling out like terms

5.1     Pull out like factors :

  b2 + 16bc  =   b • (b + 16c)

Adding fractions that have a common denominator :

5.2       Adding up the two equivalent fractions

b • (b+16c) + 16c • 4     b2 + 16bc + 64c

—————————————————————  =  ———————————————

          4                      4
