Answer:
<u>The answer is 4√5</u>
Step-by-step explanation:
Simplify 2√5 + 3√5 - √5
We can simplify this operation this way:
√5 (2 + 3 - 1) or (2 + 3 - 1)√5
Now, we resolve the operations inside the parenthesis:
√5 (5 - 1) = √5 (4) = 4√5 or (5 - 1) √5 = (4) √5 = 4√5
<u>So, the result of the simplification of this operation is 4√5.</u>
The relationship between y and x is y = 5x + 15.
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are the variables, m is the rate of change (slope) and b is the initial value of y (y intercept).
From the table, using point (5, 40) and (25, 140):
The relationship between y and x is y = 5x + 15.
