(3/4)x + (5/8) x =4x

.75. .625

.75x +.625x = 4x

1.375x = 4x

subtract 4x from each side because you want to get like terms (x) together.

equation is now
1.375-4x= 0

-2.625x= 0

-2.625× = 0
------------- -----------
-2.625 -2.625

zero can't be divided by anything so

x=0

For this case we have the following function:
f (x) = (1/6) ^ x
We must evaluate the function for x = 3
We have then:
f (3) = (1/6) ^ 3
Rewriting:
f (3) = (1/216)
Answer:
The function evaluated at x = 3 is:
f (3) = (1/216)

What is the best approximation of the value of w? 1. 4 cm 4. 0 cm 6. 0 cm 7. 3 cm.

To solve the problem we must know about Sine Rule.

The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. It is given by the formula,

$\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}$

where

Sin A is the angle and α is the length of the side of the triangle opposite to angle A,
Sin B is the angle and β is the length of the side of the triangle opposite to angle B,
Sin C is the angle and γ is the length of the side of the triangle opposite to angle C.

The value of w is 4.0 cm.
