<u>x² - 4x - 5</u> <u>x² - 3x - 10</u>
(x - 5)(x + 1) (x - 5)(x + 2)
GCF: (x - 5)
LCM: (x - 5)(x + 1)(x + 2)
Answer: (x - 5)(x + 1)(x + 2)
here's the solution,
let the length of shorter peice = x
then the lenght of longer peice = 6x + 8
now, we know that the sum of length of peices measures 99 feet,
So,
=》x + 6x + 8 = 99
=》7x = 91
=》x = 13
shorter piece length = 13 feet
longer peice length = 13 × 6 + 8 = 78 + 8 = 86 feet
USING PYTHAGORAS THEORAM,
x²+3²= 5²
x²+9= 25
x²= 25-9 = 16
x= √16
x= 4
OPTION D
First you will subtract right to left and then what ur left with is the sum.
