I need help. Work has to be shown but i don’t know how to do them
mote1985 [20]

Step-by-step explanation:

1.

1% of 500 is 5 so multiply 5 by 8 for one year. which is 40 so multiply that by 2.

1% of 500 = 5

5 × 8 = 40

40 × 2 = 80

2.

1% of 1000 = 10

10 × 5 = 50

50 × 3 = 150

3.

12 months = 6%

6/12 = 1 month

0.5 = 1 month

0.5 × 9 = 4.5 (the amount of interest for 9 months.)

800 × 4.5% = 36

4.

12 months = 7%

7/12 = 1 month ( i'll leave this in fraction form because of the decimal points.)

7/12 x 8 = 4.666667 or 4.7 rounded.

1200 × 4.7% = 56.40

You design the wooden picture frame and paint the front surface.
Hitman42 [59]

Answer:

  • a) 8x + 28
  • b) 68 in²

Step-by-step explanation:

a)

<u>Area of the frame with picture:</u>

  • A = lw
  • A₁ = (x + 4)(x + 7) = x² + 11x + 28

<u>Area of the picture:</u>

  • A₂ = x(x + 3) = x² + 3x

<u>Area of the wooden frame is the difference of the above values:</u>

  • A₃ = A₁ - A₂
  • A₃ = x² + 11x + 28 - x² - 3x
  •     = 8x + 28

b)

<u>When x = 5, the picture frame area is:</u>

  • A₃ = 8*5 + 28 = 40 + 28 = 68 in²
