The correct answer is C) (3×10⁴)(2×10²)
Explanation:
The total number of cactus plants can be found by multiplying the density of plants (d) by the area (A):
P = d · A
The area of a square can be found by the formula:
A = s²
= (175 km)²
= 30625 km²
which can be approximated to 3×10⁴ km²
The density of the cactus plants is
d = 214 /km²
which can be approximated to 2×10² /km²
Therefore, the number of plants can be approximated to:
P = d <span>· A
= (</span>2×10² /km²) · (3×10⁴ km<span>²)
= </span>(2×10²) · (3×10⁴<span>)</span>
Hence, the correct option is C)
all the sides are the same bc its an equilateral triangle
3x+10=4x+1
4x-9=3x
x=-9
the measure is 60 degrees because its an equalateral triangle
this is what i got, good luck on your hw
Answer:√5 - √2
Step-by-step explanation:
= √(5 + 2 - 2√10 )
= √{(√5)² +(√2)² - 2.√5.√2}
= √(√5 - √2)² (by identity a² + b² -2ab = ( a-b)²)
= √5 - √2
