If you divide each number by the previous one, you get:
-86 / -172 = 1/2
-43 / -86 = 1/2
-21.5 / -43 = 1/2
The common ratio is 1/2 = 0.5
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:
(x - 4)(x - 4)
x = 4
Step-by-step explanation:
x² - 8x + 16
= (x - 4)(x - 4)
x - 4 = 0
x = 4
