Answer:
The answer is 68 and 52
Step-by-step explanation:
x + y = 120
3(x - y ) = 48
We have 3x + 3y = 360
and 3x - 3y = 48
Adding we have the following:
6x = 408
x = 68
y = 120-48 = 52
Answer:
3(7x-3)
Step-by-step explanation: I factor it.
Given

Divide it by (x+1) using synthetic division, as shown below
The green line is a minus sign.
Thus,

Therefore, since the remainder is different than zero, (x+1) is not a factor of 4x^2+2x-5
<u>1 is a rational number</u> because 1 can go into 1 when dividing. <u>Irrational numbers are mostly decimals. </u>
