Step = 9
a30 = a1 + 9(30 - 1) = -4 + 9 × 29 = -4 + 261 = 267
Answer:
x = 5
Step-by-step explanation:
As it is parallelogram And we can see the diagonals bisect each other and are divided into equal parts so
2x = 15 - x
2x + x = 15
3x = 15
x = 15 / 3
x = 5
It costs $ 30240 to stain floor of the entire room
<em><u>Solution:</u></em>
<em><u>Given that,</u></em>
Sgt. Merritt has bought a house now that his tour of duty is up
He wants to stain the wood floors of the living room, which measure 18 x 14
Therefore,
length = 18 yards
Width = 14 yards
<h3><u>Find the area:</u></h3>

Thus area of wood floors is 252 square yards
<h3><u>How much will it cost to stain floor of the entire room?</u></h3>
The stain costs $120 per square yard

Thus it costs $ 30240 to stain floor of the entire room
The answer to this is C.27.3 and you would divide to get your answer.
