(a) Four cities, conveniently named A, B, C, and D, lie along a very straight road, not necessarily in that order. B is between C and D, and D is between B and A. The

distance from B to C equals the distance from A to D, which is twice the distance

from B to D. The distance from A to C is 250 mi. What is the distance from A to B?

Justify your answer.

(b) In her back yard, Carmen wants to build a swimming pool that is 12 ft by 40 ft.

She also plans to build a deck that is 6-ft wide surrounding the pool. What is the

area of the deck?

step-by-step explanation:

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
