<span>The 1/2 stretches the period from 2pi to 4pi and the amplitude stays the same. If the equation was y=2sin(x) then the amplitude would be 2.</span>
Answer:1,331
Step-by-step explanation:put 121 on top and 11 on the bottom then start multiply , or you could use a calculator / Photo-math if you’re feeling lazy
(2x + 3) • (x + 3)
2x • x = 2x^2
2x • 3 = 6x
3 • x = 3x
3 • 3 = 9
6x and 3x combine to get 9x, which when all written out is equal to your original trinomial.
