Answer:
22x^2 -10xy + 12x
Step-by-step explanation:
To add and subtract polynomials, combine only like terms. When doing it vertically, stack polynomials and line up the same bases and exponents. Once this is done, simply add and subtract the coefficients.
10x^2 + 12xy + 4x
+ 12x^2 -22xy + 8x
_________________
22x^2 -10xy + 12x
Here we added 10 + 12 = 22, 12 + -22 = -10 and 4 + 8 = 12.
Answer: 2 inches
Explanation: The area formula is length times width (L*w=a). We know that the area is 64in^2 (a=64) and the length is 32in (L=32), so we put those values into the equation and get 32*w=64. We then get w by itself by dividing both sides by 32, and get w=2. so the width is 2 inches.
co-ordinates of point G are (1,2)
co-ordinates of point H are (3,-3)
so, by distance formula :
so, it is root(29) or 5.38 units

use the formula V*t=x so if the velocity is 8 2/3 miles per hour and you need to travel 5 1/5 miles then (8 2/3)*t=5 1/5,
so t=(5 1/5)/(8 2/3)= .6 hours
