Hannah wrote down the set of number below (3,4,5,6) her friend wrote down the equation below 4x 2=18 which number from Hannah's set makes the equation true?

4

Step-by-step explanation:

The equation written by her friend is 4x+2=18.

To find the number from Hannah's set (3,4,5,6) that will make the equation true, we will need to find the value of x in the equation and check if the resulting value of x is a member of the set. From the equation;

4x = 18-2

4x = 16

Dividing both sides by 4 we have;

4x/4 = 16/4

x = 4

Therefore the number from Hannah's set that makes the equation true is 4.

i am thinking c. sorry if im wrong .

step-by-step explanation:

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,
