Okay. I'll use a formula that my math teacher taught me.
Answer:
1144.78 Km^2
Step-by-step explanation:
If the forest covers an area of 3400 km^2 and it decreased by 7%, the new area covered after a year will be equal to 3400 less the product of 3400 and 7%
= 3400 - 7% * 3400
= 3400 (1 - 0.07)
After the second year, the area becomes
= 3400 (1 - 0.07) - 7% * 3400 (1 - 0.07)
= 3400 (1 - 0.07)(1 - 0.07)
= 3400 (1 - 0.07)²
Following this pattern, the area after 15 years
= 3400 (1 - 0.07)^15
= 1144.782931 km^2

Answer:
A) $15
Step-by-step explanation:
let x represent the regular price of the mirror
so, 20% of x = 3
20/100 * x = 3
20x = 300
x = 300/20
x = 15
Hence, the regular price of the mirror is $15
Answer:
x = 50
m∠D = 150°
m∠F = 30°
Step-by-step explanation:
supplementary angles are two angles whose sum is 180° ∠D + ∠F = 180°
3x + x - 20 = 180
3x + x = 180 + 20
4x = 200
x = 200/4
x = 50
D = 3*50 = 150
∠D = 150°
F = 50 - 20 = 30
∠F = 30°
