7 0

Answer:

144

Step-by-step explanation:

Find: Length of segment BC

CD+DB=BC

3x+8+4x+10=BC

7x+18=BC

BC also equals 8x (given on the screen shot)

7x+18= 8x

x=18

18 times 8 = 144

Check:

3( 18) + 8 + 4(18) + 10

54+8 + 72+10

64+ 80= 144  TRUE

What is the answer for 1/4 ( 12x + 24 ) -9x
Gekata [30.6K]

The final expression is -6x+6

Step-by-step explanation:

The expression that we have is

\frac{1}{4}(12x+24)-9x

In order to solve the expression, we start by applying the  distributive property to the bracket. We get:

\frac{1}{4}\cdot 12x + \frac{1}{4}24 -9x

Simplifying,

3x+6-9x

Now we add the two terms in x, and we find:

(3x-9x)+6=\\-6x+6

Which is the final expression.
