2(3 + 9x) - 2x
= 6 + 9x - 2x <----------------mistake right here
= 6 + 7x
Correct:
Expanding by using distributive property
2(3 + 9x) - 2x
= 2* 3 + 2 * 9x - 2x
= 6 + 18x - 2x
= 6 + 16x
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

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

Area of Rectangle = legnth × width
= 180cm × 50cm = 9000 cm2

Area of the electronic board is 9000 cm2
Hello!
The mean is the average. The median is the middle number of the data set, in terms of quantity. The mode is the number that appears the most. The range is the difference between the largest and smallest numbers in the set.
Therefore, our answers are below.
