2a+7+4ahow many terms? how many variables? any like terms? yes noif yes, which ones? what are the coefficients? any constants? yes noif yes, which ones? simplify the expression by combining like terms and constants: how many terms now?

one that is bigger than 3 1/2

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,

c: lkllmn.
