17 pieces. She had two and she had to have 15 to give to the children. If each child got 3 and there is 5. This turns into 3*5=15. Then you would add 15+2 to get 17
Answer:
B.) Open circle on 3 and all numbers to the left shaded
Answer:
(x+3) and (x-6) are factors
Step-by-step explanation:
The given expression is :
x²-3x-18
We need to find the factors of the above expression.
We can solve it using middle term splitting. We find two integers such that there product is -18 and sum is -3. These two numbers can be -6 and 3.
x²-3x-18 = x²-6x+3x-18
= x(x-6)+3(x-6) [taking common terms]
= (x+3) (x-6)
Hence, the factors of the above expression is (x+3) and (x-6).
