Since 4 des not contain the variable to solve for, Y=-4+x
128,147.............................................
First find the answer without decimals
√225= 15
2.25 has two decimal places, so therefore the square root must contain 1 decimal place.
√2.25= 1.5
Final answer: 1.5
ps -1.5 is also correct but I'm not sure if that's what your teacher wants.
Answer:
5x / (x - 4)
Step-by-step explanation:
(x + 1)/(x - 4) • 5x/(x + 1)
Method 1:
Cancel out x + 1
Leaving 5x/(x - 4)
Method 2:
(x + 1)/(x - 4) • 5x/(x + 1)
Multiply numerator and denominator separately
= 5x(x + 1) / (x - 4)(x + 1)
Cancel out (x + 1) in the numerator and (x + 1) in the denominator
= 5x / (x - 4)
Therefore,
(x + 1)/(x - 4) • 5x/(x + 1) = 5x / (x - 4)
