Let:
x = Pastries ordered
y = Cost of order

For each pastry Cole ordered, the cost of the order increased by a fixed amount of $1.55
Step-by-step explanation:
(x+3)(x-5)
= x²-5x+3x-15 = x²-2x-15
But the given polynomial x³-15
So it is not the correct factorization.
Again, (x-3)(x+5)
= x²+2x-15
But the given polynomial x³-15
So it is not the correct factorization.
Again , (x+3)(x²-4x+5)
= x³-4x²+5x+3x²-12x+15
= x³-x²-7x+15
But the given polynomial x³-15
So it is not the correct factorization.
So , optionD is the correct answer
The product of the gift and another sum is 1 (27,18)
8 8/3
Explanation:
(8 2/3)4
(8 2*4/3)
8 8/3
8 8/3=256=(8 2/3)4
Answer:
The number is 13.
Step-by-step explanation:
We are given the following in the question:
Let x be the variable, then according to the question
"The sum of eight and eleven times a number is 151"
We can write the equation:

Solving the equation, we can write:

Thus, the number is 13.
