Try plugging them in, might seem tedious, but it's the best way to practice. if you plug in a pair and the left side of the equation is less than or equal to 6, it's the right answer.
Check your textbook on the Remainder Theorem.
any divisor that yields a remainder of 0 from the dividend, IS a factor of the dividend.
namely, if x⁴+3x³-6x+8 ÷ x+4, gives a remainder of 0, then x+4 IS a factor of x⁴+3x³-6x+8.
The formula for P and B is 4P + 10B = 7
Given,
The number of batteries in a packet = 4 batteries
The number of batteries in a box = 10 batteries
Sarah bought P packets and B boxes of batteries
The total number of batteries Sarah bought = 7 batteries
We have to write an expression;
Here,
4 batteries in a packet.
Sarah bought P packets of battery.
So, she bought 4P batteries
Then,
10 batteries in a box
Sarah bought B boxes of battery
So, she bought 10B batteries
That is,
Sarah bought a total of 4P + 10B batteries which is 7 batteries
Therefore,
The formula for P and B is 4P + 10B = 7
