(x^4)(3x^3-2)(4x^2+5x)
=(3x^7-2x^4)(4x^2+5x)
=12x^9+15x^8-8x^6-10x^5
answer: 12x^9+15x^8-8x^6-10x^5
<h2>
Answer:</h2>
<u>The length is</u><u> 250 meters</u>
<h2>
Step-by-step explanation:</h2>
If we look at the left corner of the diagram we see a scale. According to the scale factor of the map
1 cm :1000 cm
The length of the lap on the map is 25 cm
So (25 × 1000) = 25000 cm
Since
1 meter = 100 centimeter
So the actual length of the lap = 25000 ÷ 100 = 250 meters
Step-by-step explanation:
The answer is in the pic above
Given:
1st week: caught 45 salamanders and put leg bands on them
2nd week: caught 50 salamanders and 3 have leg bands
3/50 = 0.06 of the salamander population have leg bands.
45 / 0.06 = 750 total number of salamanders
<span>45/750 = 0.06 or 6% </span>
The reasonable estimate of the number of salamanders by the pond is 750 salamanders.
