Which of the following expressions has a value of 3? select all that apply. -6 ÷ -2 4 - (-1) (-) (-2) - 1 15 ÷ -5 4 + 1

-6 ÷ -2 and  (-1)(-3)

Step-by-step explanation:

we need to find the expression that gives the value of 3

-6 ÷ -2 , is 3 because negative and negative is positive

4 - (-1), which is not equal to 3

(-1)(-3), negative times negative is positive

(-2) - 1, which is not equal to 3

15 ÷ -5 ,, not equal to 3

4 + 1,

-6 ÷ -2 and  (-1)(-3) gives us the value of 3

the answer is c

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,
