<span>3x</span>² <span>- 8x -3 = 3x</span>² - 9x + x - 3 =
= 3x² - 9x + x - 3 = 3x* ( x - 3) + 1* (x - 3) =
= 3x * (x - 3) + 1 * (x - 3) = (3x + 1) (x - 3)
Answer (3x + 1) (x - 3)
Answer:
= 
Step-by-step explanation:
The given expression is :

We need to find this expression is equal to what.

Hence,
is equal to
. Hence, the correct option is (c).
Step-by-step explanation:
a. (0.60x + 0.70y)- 50 = 10
<=> 0.60x + 0.70y = 60
b. (x+y) = 5(x-y)
x+y=5x-5y
<=> 4x - 6y = 0
I chose 40! thought it was to only logical answer
