B² + a²b
In this equation you have to plug into it the related values of a=2, b=-3
That is (-3)² + (2²).(-3)==> (-3)(-3) + (2)(2)(-3)
9 - 12 = - 3
Answer:
2/3 begins w a 2 and 1/3 begins w a 1. thats the difference.. hope this helped :)
Step-by-step explanation:
Answer:
Four
Step-by-step explanation:
Let's expand and see how many nonzero terms:
⇒ (x+4)(2x²+3x+9)-3(x³-2x²+7x)=
⇒ 2x³ + 3x² + 9x + 8x² + 12 + 36 - 3x³ + 6 x² - 21 x=
⇒ - x³ + 17x² - 12x + 12
As we see the expression has four nonzero terms
1) Take the perimeter and divide it by 4.
2) Take the answer from step 1 and square it (multiply by itself)
The correct answer is 12
Set up a ratio and then solve. See paper attached. (:
