Answer:

c = 45h + 25

Step-by-step explanation:

The only difference between what the electrician used to charge and what he/she charges now is an increase of $5. Therefore, instead of charging $40 he is now charging $45. Using this new information we can create the following equation to calculate the total cost of a job. We do this by multiplying the cost per hour ($45) by the total number of hours (h) and then adding the surcharge.

c = 45h + 25

Find the perimeter and area of each figure.​
Sergio039 [100]

Answer:

  1. A = 2x; P = 4x+2. A = 4; P = 10.

  2. A = y² +2; P = 4y +2. A = 27; P = 22.

Step-by-step explanation:

1. The area is the sum of the marked areas of each of the tiles:

  A = x + x

  A = 2x

__

The perimeter is the sum of the outside edge dimensions of the tiles. Working clockwise from the upper left corner, the sum of exposed edge lengths is ...

  P = 1 + (x-1) + x + 1 + (x+1) + x

  P = 4x +2

__

When x=2, these values become ...

  A = 2·2 = 4 . . . . square units

  P = 4·2+2 = 10 . . . . units

_____

2. Again, the area is the sum of the marked areas:

  A = y² + 1 + 1

  A = y² +2

__

The edge dimension of the square y² tile is presumed to be y, so the perimeter (starting from upper left) is ...

  P = y +(y-2) +1 +2 +(y+1) +y

  P = 4y +2

__

When y=5, these values become ...

  A = 5² +2 = 27 . . . . square units

  P = 4·5 +2 = 22 . . . . units
