Step 1. Distribute sum groups
x(x^2 - 3xy + 2y^2) +y(x^2 - 3xy + 2y^2)
Step 2. Distribute
x^3 - 3x^2y + 2xy^2 + y(x^2 - 3xy + 2y^2)
Step 3. Distribute
x^3 - 3x^2y + 2xy^2 + yx^2 - 3y^2x + 2y^3
Step 4. Collect like terms
x^3 + (-3x^2y + x^2y) + (2xy^2) + 2y^3
Step 5. Simplify
Answer: x^3 - 2x^2y - xy^2 + 2y^3
Answer:
Calgary is the coldest
Step-by-step explanation:
The simple way to determine this will be to change the value of temperatures given in Fahrenheit to Celsius
32 F = 0°C
Formula to apply will be (T-32)×5/9 -------------where T is temperatures in Fahrenheit
Bangor is -3F-------------------change to Celsius
(-3-32)×5/9 =-35 × 5/9 = -19.44°C
Fairbanks is -12 ------------------------change to Celsius
(-12-32)×5/9 = -44 × 5/9 = -24.44°C
Fargo is -8 F ---------------------Change to Celsius
(-8-32)×5/9= -40×5/9 = -22.22°C
Calgary is -15 F-------------------------Change to Celsius
(-15-32)×5/9 = -47×5/9 = -26.11°C--------------coldest
(9-4) /9 = 0.56 = 56% discount
Answer:
Choices are:
p>30
p<30
p=30
not enough information to tell
Answer is p>30
Step-by-step explanation:
Since there are more boys than girls, there must be at least 9 boys. Plug into equation: (b+8) represents number of students. If they each have at least 2 pencils we would use 2(b+8). Plugging in 9 for the boys we have: 2(9+8)=?
2(17)=34. So with the minimum number of boys there would be at least 34 pencils, so the answer is p>30
-2x3 (5+3-83x3) then just put that in a calculator or do it in your head
