A farmer plants crops in several rows starting with 3 crops in the first row, 12 in the second and 48 in the third row. The farmer continues the pattern for the rest of the row crops What equation represents the number of crops in row?
G=3n+1
G=3n+4
G=3(4)n
G=3(4)n-1

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

ok then what happened.

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
