Step 2 and all that follows is wrong because it should equal 20
Answer:
<u>(a): 9x + 45</u>
Option A, 9(x + 5) because it distributes into 9x + 45
Option B, 9 * x + 9 * 5 because it multiplies into 9x + 45
<u>(b): 13 + 9y - 3 - y</u>
Option D, 8y + 10 because it combines into this number
Type into a calculator 2000*(3/8)
The answer is 750
Im not entirely sure but, if you're on plato answer D is correct
model 1 has a random pattern and is fit for the data
87% i think but don't hold me to that
you just do 65/5=13% so 13% is missing so you take that from 100 which gives 87
