Firs you would do 4b-15b and get -11b. Next you would do -7+3 and get -4. The final expression would be -11b-4
Lets put the problem all together first
1) p^2+mn
2^2+0(-1)
Now we start
2x2=4
0x-1=0
4+0=4
Your answer should be 4:)
2) m+np^2
0+-1(2)^2
2x2=4
-1x4=-4
0+-4=-4
Your answer should be -4:)
The answer is (3)2. I guess that that is the answer but i’m nots sure, lol.
