Scale drawing of the electronics board
lora16 [44]

Area of the electronic board is 9000 cm2

Step-by-step explanation:

Write ratios to represent the unknown actual length and width of the display to the scale length and width of the display.

The Electronic board always seems like a rectangular shape

Length= scale÷Actual = 5/36 = 5×36 = 180cm

Length= scale÷Actual = 5/36 = 5×36 = 180cm

Width=scale÷Actual = 1/50 = 1×50 = 50cm

Width=scale÷Actual = 1/50 = 1×50 = 50cm

Area of Rectangle = legnth × width

                         = 180cm × 50cm = 9000 cm2

= 180cm  × 50cm = 9000 cm2

Area of the electronic board is 9000 cm2

From the sum of 5-9i and -4+7i, subtract 14-3i
Kryger [21]

Answer:

Subtract: 5 - 9i = 5-9i  

Add: the result of step No. 1 + (-4) = (5-9i) + (-4) = (5-4) + (-9i) = 1-9i  

Add: the result of step No. 2 + 7i = (1-9i) + 7i = 1 + (-9+7)i = 1-2i

Subtract: 1 - 2i = 1-2i  

Subtract: the result of step No. 1 - 4 = (1-2i) - 4 = (1-4) + (-2i) = -3-2i  

Add: the result of step No. 2 + 7i = (-3-2i) + 7i = -3 + (-2+7)i = -3+5i

Step-by-step explanation:

Correct me if I'm wrong pls and ty :).

Hope this helps.
