Which value is equivalent to x+4/4+x? a. -4 b. -1 c. 1 d. 4

Hello :

(x+4)/(4+x) = (x+4)/(x+4)  = 1   ( answer : C )  but x+4 no : 0

C. 1

Step-by-step explanation:

Commutative property says that changing the order of the operands does not change the result. This can be expressed as:

Using the previous information, we can say:

And rewrite the equation as:

Since the numerator and denominator are the same:

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
