Answer:
=14x² −3x −1
Step-by-step explanation:
simplifying step-by-step.
9x2+5x2+5x−3−(8x−2)
Distribute the Negative Sign:
=9x2+5x2+5x−3+−1(8x−2)
=9x2+5x2+5x+−3+−1(8x)+(−1)(−2)
=9x2+5x2+5x+−3+−8x+2
Combine Like Terms:
=9x2+5x2+5x+−3+−8x+2
=(9x2+5x2)+(5x+−8x)+(−3+2)
=14x2+−3x+−1
Answer:
=14x2−3x−1
Answer:
1.5 or infinite
Step-by-step explanation:
For the second one, 8x+4=16, suppose x is 1.5 (1 1/2), then 8x1.5 is 12, then 12+4 is 16.
As for the first one, their is infinite possibilities. If x equals 3 and y is 2, then 8x3=24 and 4x2=8, and 24-8=16. Another example is if x equals 4 and y is 4. Then 8x4=32 and 4x4=16, then 32-16=16. And one final example to make sure you understand. X equals 10 and y equals 20. 8x10=80 and 4x16=64, then 80-64=16.
The actual distance between Yappy city and Quiet city when it is 23 cm in map is 9.2 miles.
What is scaling ?
It is the technique to resize drawing with comparing to actual size of object which uses proportion or ratio. For example, Mapping of earth, drawing prototype of automobiles.
It is given that :
The distance on the map between Yappy city and Quiet city is 23 cm
and,
5cm = 2 miles
now, for 1 cm on map it is equal to 2/5 miles of actual distance.
Therefore to find the actual distance of 23 cm in map we simply multiply 23 with 2/5 :
actual distance :
2/5 x 23 = 9.2 miles
Therefore, the actual distance between Yappy city and Quiet city is 9.2 miles.
