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
*Hint: The formula for finding the surface area of a rectangular prism is SA = 2 (wh + lw + lh).
Now, just plug in and solve.
SA = 2 [(10)(8) + (12)(10) + (12)(8)]
SA = 2 (80 + 120 + 96)
SA = 2 (296)
SA = 592.
The surface area of Rita's room is 592 feet squared.
I assume you mean to find (a) the GCF (greatest common factor) and (b) the least common multiple LCM.
To do both parts, you need ot factor the polynomials.
x^2 - 3x + 2 = (x - 2)(x - 1)
x^2 - 4x + 4 = (x - 2)(x - 2) = (x - 2)^2
(a) GCF: use only common factors with lower exponent.
The GCF is x - 2
(b) LCM: use common and not common factors with the larger exponent.
The LCM is (x - 2)^2(x - 1)
