Answer:
=5x^2+4x−5
Step-by-step explanation:
Let's simplify step-by-step.
3x2−5x+1+2x2+9x−6
=3x2+−5x+1+2x2+9x+−6
Combine Like Terms:
=3x2+−5x+1+2x2+9x+−6
=(3x2+2x2)+(−5x+9x)+(1+−6)
=5x2+4x+−5
Hi!
Alrighty, so there are 5 sets of 50 in 250 (250 divided by 50), so just take 50 times 12 and get 60! Hope that helped :)
The answer is 9.
To calculate this, we will use Galileo's square cube law, used to describe the change of the area or the volume of the shape, when their dimensions increase or decrease. The formula used for change of the area is

A₂ - the area after the change,
A₁ - the area before the change,
l₂ - the dimension after the change,
l₁ - the dimension before the change.
It is given:
l₁ = 1 cm
l₂ = 3 cm
Let's use this formula for the mentioned triangle:

Therefore, the area of the triangle was multiplied by 9.
Answer:
10 miles per hour
Step-by-step explanation:
there are 60 minutes in an hour once you covert you have that it took 1.17 hours then there are 5280 feet in a mile so you convert and get 12.075 miles
you divide
12.075/1.17 = 10.3205128
then you simplify to the nearest whole number and get 10
