Answer:

  a) 18

  b) 6

Step-by-step explanation:

a) The proportion can be written as ...

  MS/LC = 3/2 = MS/12

Multiplying by 12 gives ...

  MS = 12(3/2) = 18

There are 18 buildings in the Main Street district.

__

b) The proportion of stores to total buildings in the Main Street district is ...

  stores : non stores = 1 : 2

  stores : (stores + non-stores) = 1 : 3

1/3 of the buildings in the MS district are stores. There are ...

  (1/3)(18) = 6 . . . stores in the Main Street district

please someone help with this question we are doing angle properties in polygons and I can't figure out b) i will give brainest
labwork [276]

 Answer:

a)  a = 60°  b = 60°   c = 120°  d = 60°

b)  a = 140°   b = 20°  c = 60°    d = 60°

Step-by-step explanation:

a)   Sum of the angles of a hexagon = (6 - 2)180 = 720

Since the hexagon is regular, c = 720/6 = 120

a and c are supplementary, so a = 180 - 120 = 60

d = 120/2 = 60

b)  

sum of the angles of a nonagon = (9 - 2)180 = 1260

a = 1260/9 = 140

140 + 2b = 180

         2b = 40

           b = 20

c = 60  and d = 60  (This is really difficult to explain with the vertices being labeled)

ONLY GIVING BRAINLYEST IF YOU ANSWER QUICKLY AND CORRECTLY
k0ka [10]

Answer:

B and D

Step-by-step explanation:

First, you have to solve the first equation. (Hint: you use the distributive property.)

2(5x + 2 + x)

10x + 4 + 2x

12x + 4

We can already see that B is correct and A is incorrect.

Now to solve C and D.

C = 2(5x + 3)

10x + 6

This is incorrect.

D = 2(6x + 2)

12x + 4

This is correct.

write a simplified polynomial expression in the standard form to represent the area of the rectangle below x-4 5x+2
Ann [662]

The area of the rectangle is 5x^{2} -18x-8

Explanation:

One side of the rectangle is x-4

The another side of the rectangle is 5x+2

The formula to find the area of the rectangle is length × width

Area = length × width

Substituting the values, we have,

\begin{aligned}\text { Area } &=(x-4)(5 x+2) \\&=5 x^{2}+2 x-20 x-8 \\&=5 x^{2}-18 x-8\end{aligned}

Thus, the area of the rectangle is 5x^{2} -18x-8
