Answer:
x+5
Step-by-step explanation:
Given:
Dividend= x4 + 5x3 – 3x – 15
Quotient=(x3-3)
As per the rule of division of polynomial:
Dividend = Divisor × Quotient + Remainder
Divisor= required polynomial p(x)
remainder=0
x4 + 5x3 – 3x – 15= p(x) *(x3-3) + 0
p(x)=x4 + 5x3 – 3x – 15/x3-3
By long division we get
p(x)= x+5 !
let total earnings = x
and number of hours = y
so x=60+5.25y is the formula
so for 4 hours replace y with 4
x = 60+5.25(4)
x = 81, so for 4 hours she made $81
Answer:
The naswer to your question is: letter c)70
Step-by-step explanation:
Data
2 skeins of yarn cost $7
8 skeins of yarn cost $28
total = 20 skeins
cost = ?
Equation = she need s to buy 2 skeins of 8 a 2 skeins of 2
cost = 2 x $28 + 2 X $7
cost = 56 + 14
cost = $70
Answer:
Step-by-step explanation:
We have been given the equation:
And
Second equation can be rewritten as:
We will solve the equations:
(1)
(2)
Multiply equation (1) by 5 and equation (2) by 3 we get:
(3)
(4)
Now, subtract (4) from (3) we get:
Now substitute in equation (1) we get:
