Answer: 21m
Step-by-step explanation:
From the question, we are informed that the scale drawing of a playground is 4 cm wide and 6 cm long and that the playground is 14 m wide.
Let the length of the playground be represented by x. Therefore,
4/6 = 14/x
4 × x = 14 × 6
4x = 84
x = 84/4
x = 21
Therefore, the length is 21m
Answer:
4 and 4?
B 9, -9
x^2 - 81 = 0
Add 81 to each side
x^2 = 81
Take the square root of each side
sqrt(x^2) = sqrt(81)
x = ±9
12.4968
