Question 2 Determine if (x-3) is a factor to the polynomial P(x) = 2x³ +5x²-28x - 15. (3 marks)​
tangare [24]

Answer:

(x - 3) is a factor of P(x)

Step-by-step explanation:

if (x - 3) is a factor of P(x) then P(3) = 0

P(3) = 2(3)³ + 5(3)² - 28(3) - 15

      = 2(27) + 5(9) - 84 - 15

      = 54 + 45 - 99

      = 99 - 99

      = 0

since P(3) = 0 then (x - 3) is a factor of P(x)

Stephanie wants to buy s tomato plants.
max2010maxim [7]

Answer:

Required Expression : 7·(s + d) - 25

Step-by-step explanation :

Cost of each plant both buys = $7

No. of plants Stephanie wants to buy = s

Total cost of plants bought by Stephanie = 7·s

No. of plants Diego wants to buy = d

Total cost of plants bought by Diego = 7·d

Total cost = 7·s + 7·d

                 = 7·(s + d)

Discount applied through coupon = $25

So, Total cost of all their plants with discount = 7·(s + d) - 25

If an item that originally cost $13 is increased to $19, what is the percentage of increase in the item?
Evgesh-ka [11]
Original cost (OC) = $13

New cost (NC) = $19

Percentage increase = \frac{NC - OC}{OC} *100 =  \frac{19 - 13}{13} * 100 =  \frac{6}{13} * 100

= 46.15 %
