Answer:

30 and 6

Step-by-step explanation:

Given that R is the midpoint of QS , then

RS = QR , that is

5x = 3x + 6 ( subtract 3x from both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Then

QS = QR + RS

     = 3x + 6 + 5x

     = 8x + 6

     = 8(3) + 6

     = 24 + 6

     = 30

------------------------------------------------------------------

Similarly

QR = RS , that is

6x - 9 = 2x - 1 ( subtract 2x from both sides )

4x - 9 = - 1 ( add 9 to both sides )

4x = 8 ( divide both sides by 4 )

x = 2

Then

QS = QR + RS

      = 6x - 9 + 2x - 1

      = 8x - 10

      = 8(2) - 10

      = 16 - 10

      = 6

Apply the distributive property to create an equivalent expression. 12(2a - 6b+ 8) = 2 1 ​ (2a−6b+8)
liberstina [14]

Answer:

a+4=11b

Step-by-step explanation:

Distributive property in mathematics means to multiply the sum by a number of two or more add-ons will provide the same result that each add-on multiplies by a single number and then together add the products.

for example a( b+c) = ab+ac

Therefore, applying distributive property in asked eapression

12(2a - 6b+ 8) = 21(2a−6b+8)

24a+72b+96 = 42a-126b+168

198b=18a+72

9a +36=99b

3a+12=33b

a+4=11b

Please help me it would mean a lot

42.5 i think

The whole angle is 127 minus the angle we know (32) this leaves us with 85 for the rest of the angle but we still have to deal with the angle bisector so we divide it by 2 leaving us with 42.5 I'm pretty sure.
