Please someone help me with this because i dont understand it at all ;-; A rectangle with width of 5. There is a vertical line that splits rectangle into two sections with different lengths. One length is x the other is 3.

5(x + 3) represents the area of the rectangle above. Which expression below is equivalent by the Distributive Property?

5x + 3
(5 + x) + 3
5x + 15
(x + 3) ⋅ 5

5x+15

Step-by-step explanation:

5(x+3)

5 times x, then to the next which is 3

5x+15

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

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
