Algebraic expression for 15x + 8

1 answer:

5 0

Yes, this is an algebraic expression, and is the simplest possible. Cannot be simplified further, and cannot be factored.

If we know the value of x, we can evaluate it to a number, otherwise, it stays as it is.

Or, perhaps the question is not complete.

FIRST TO ANSWER, would be marked as brainliest:)

boyakko [2]

Answer:

100 Cos 40° + 100 Sin 40° ≈ 141 yards

Step-by-step explanation:

From the diagram, side x is adjacent to the angle 40° while side y is the opposite to that same angle

This means that;

Cos 40° = x/100

x = 100 Cos 40°

Sin 40° = y/100

y = 100 Sin 40°

Therefore, total distance walked = x + y

" = 100 Cos 40° + 100 Sin 40° ≈ 141 yards
