I was not sure if the x is multiplication or not. if it is its then its -23 if its not its 5x-28. I hope this helps.
Find the area of the room by multiplying the length by the width:
Area of room = 15.5 x 18.5 = 286.75 square feet.
Divide the total area of the room by the area of a box to find the number of boxes needed.
286.75 / 25 = 11.47
Since you can't buy a partial box, round up to the nearest whole number.
You need B. 12 boxes total.
Answer:
∠ B = 19°
Step-by-step explanation:
note ∠ C = 90° ( angle in a semi- circle )
The sum of the 3 angles in the triangle = 180°, thus
∠ B = 180° - (90 + 71)° = 180° - 161° = 19°
Answer:
(5n) / m^2
Step-by-step explanation:
45m^2n^4
---------------
18m^4n^3 may be factored into m, n and constant terms:
45 m^2 n^4
----- * ---------- * -----
18 m^4 n^3
45/18 reduces to 5/2.
m^2 / m^4 reduces to 1 / m^2.
n^4 / n^3 reduces to n. 5n
Multiplying these results together produces: --------
m^2
