2 answers:
Answer: 7
Step-by-step explanation:
- 2x(3x-5) -3(x-3)
- 2(2)(3(2)-5) -3(2-3) First you substitute 2 for all the x's. The twos in . parentheses represent multiplication.
- 4(6-5) -3(2-3) Second, you multiply 2 by 2, which equals 4, . and multiply 3 by 2, which equals 6.
- 4(1) -3(-1) Next, you solve the problems in the . parentheses, which is 6 minus 5 is 1, and 2 . minus 3 is -1
- 4-(-3) Next, you multiply 4 by 1, which is 4, and . multiply 3 by -1.
- 4+3 Since two negatives make a positive, the . equation changes to 4 plus 3.
- 7 Finally, you add 4 plus 3 and get 7.
P.S: Sorry about the random periods. I had to put them in to format it like that.
