Answer:
Sachet town is 12km from the airport
Step-by-step explanation:
In this question, we are asked to calculate the distance from sachet town to the airport.
This can be calculated by referring to a diagrammatic representation. Please check attached file.
Let’s proceed with the calculations however.
From the question, we can see that we have formed a Right angled triangle from the diagram and we need to calculate the distance x.
Mathematically;
x^2 + 16^2 = 20^2
x^2 = 20^2 - 16^2
x^2 = 400 - 256
x^2 = 144
x = sq.rt of 144
x = 12km
Answer: x + 6
Step-by-step explanation:
We will use the order of operations, also known as PEMDAS. See attached. Please note that we cannot do what is in the parentheses first because we have a variable, so we will distribute the 2 into it. Since this is an expression, I do not believe we can fully solve for x, but can only simplify.
Given:
2(3/5x+3)
Distribute:
2 * (3/5x) + (2 * 3)
6/5x + 6
Answer:
x + 6
