Options:
A. –3(x + 3)
B. 3(x + 3)
C. 3(–x – 3)
D. –3(x – 3)
Answer:
A and C
Step-by-step explanation:
Given
Required
Factorize
The options are not given; So, I'll answer on a general term
Express -9 as -3 * 3
Then factorize 3 out of the expression as:
Another way is to factor -3 out of the expression as:
14 of the machine that cost $150 was sold and 8 of the machine that cost $225 was sold.
To solve this problem, we would write a system of linear equations.
We can proceed to write our equations now.
From equation 1
put equation (iii) into (ii)
Since we know the number of y, we can simply substitute it into equation (i) and solve.
From the calculations above, 14 of the machine that cost $150 was sold and 8 of the machine that cost $255 was sold.
