Answer:
x = 1
Step-by-step explanation:
Sum the coefficients of the polynomial, that is
1 - 6 + 11 - 6 = 0
Hence x = 1 is a root and (x - 1) is a factor of the polynomial
Answer:
3a+5p= 45
Step-by-step explanation:
If a bag of apples costs $3 and a bag of pears costs $5 and you buy 11 bags that costed 45$, then to find out how many bags you bought for each you would need to set up an equation. I go this equation by a being amount of bags of apples and p being amount of bags of pears. since each bag of apples cost $3 and you do not know how many you got you would use 3 times amount of bags of apples (3a) this would be 3a because each bag costs 3 dollars and since you do not know how many bags of pears you bought you would use 5 times the amount of bags of pears (5p) this would be 5p because each bag of pears costs 5 dollars. It equals 45 because you spent $45 total.
