First find the total area of the building.
44ft x 74ft = 3256ft^2
Next, since you have 24 tiles per box, each covering 1ft^2 of space, find the number of boxes you need to supply the minimum number of tiles needed to fill the area.
3256ft^2 ÷ 24 = 135.6 boxes
Since you are finding the minimum number of boxes to completely fill the given area, round up.
Answer = 136 boxes
Your factoring answer is: (x^2+25)(x+5)(x-5)
Answer:
Step-by-step explanation:
The shaded region is the difference of areas of semicircle AB and triangle ABC.
ABC is right triangle as AB is diameter, so C is right angle.
<u>Area of semicircle:</u>
- A = 1/2πr² = 1/2*3.14*4² = 25.12 cm²
<u>Area of triangle:</u>
- A = 1/2BC*AC = 1/2*4*
= 2
= 13.86 cm²
<u>Shaded are is:</u>
- 25.12 - 13.86 = 11.26 cm²
The answer is 8a + 12
here's my work
4(2a + 3)
4 times 2a is 8a
then 4 times 3 is 12
