Answer:
70 + 4D
Step-by-step explanation:
- (2 x 100) + (7 x 10) + (4 x D) + (2 x 100)
- (200) + (70) + 4D + 200
-200 + 70 +4D + 200
-130 + 4D + 200
70 + 4D
Answer:
14 cm
Step-by-step explanation:
Use the formula for the area of a square, a = s², where s is the side length of the square.
Plug in 196 as the area, then solve for s.
a = s²
196 = s²
14 = s
So, the length of the pathway is 14 cm

The answer is <span>C. 546.
If a population decreases by 11%, that means that 89% (100% - 11% = 89%) of cheetahs remains each number. 89% can be expressed as 0.89, so to calculate the change of the population, we must each year multiply the number of cheetahs by 0.89.
After 1 year: 1750 * 0.89 </span>≈<span> 1558
</span>After 2 years: 1558 * 0.89 ≈<span> 1387
</span>After 3 years: 1387 * 0.89 ≈<span> 1234
</span>After 4 years: 1234 * 0.89 ≈<span> 1098
</span>After 5 years: 1098 * 0.89 ≈<span> 977
</span>After 6 years: 977 * 0.89 ≈<span> 870
</span>After 7 years: 870 * 0.89 ≈ 774
After 8 years: 774 * 0.89 ≈<span> 689
</span>After 9 years: 689 * 0.89 ≈<span> 613
</span>After 10 years: 613 * 0.89 ≈<span> 546</span>
