Answer:
<h3>Figure 1</h3>
- Perimeter of base = 5 + 5 + 8 = 18 ft
- Base area = 1/2(8)(3) = 12 ft²
<u>Surface area:</u>
- S = 18*7 + 2*12 = 150 ft²
<h3>Figure 2</h3>
<u>Surface area of cube:</u>
- S = 6a² = 6(2.5)² = 37.5 m²
<u>Surface area of prism:</u>
- S = 2(11 + 9)(7) = 280 m²
<u>Overlapping area:</u>
<u>Surface area of composite figure:</u>
- S = 280 + 37.5 - 2(6.25) = 305 m²
Answer:
3(2x-5)=6x+k
6x-15=6x+k
6x-6x=k+15
0=k+15
k=-15
Step-by-step explanation:
Yes, because both of them have a 70 degree angle on T and W
(8x-5)(2x+1)
Check: 16x^2+8x-10x-5
16x^2-2x-5
So to solve this you would need to do 14 / 4 to find how many more people there are, and that gives you 3.5 Now you would need to multiply 480 by 3.5, giving you 1680.
So the answer is 1.68 kg
