1. 4m + 2mp + 3p
2. 12r + 13pr + 24p
3. 6h^2 + 19h + 15
4. 20y^2 + 11y - 3
5. -9p^2 - 4mn + 6mp + 6np
Step-by-step explanation:
1. m(4 + p) + p(3+ m)
4m + mp + 3p + mp
4m + (mp + mp) + 3p
4m + 2mp + 3p
2. 4r(3 + 4p) + 3p(8 -r)
12r + 16pr + 24p + -3pr
12r + (16pr - 3pr) + 24p
12r + 13pr + 24p
3. (3 + 2h)(5 + 3h)
3(5 + 3h) + 2h(5+3h)
15 + 9h + 10h + 6h^2
6h^2 + 19h + 15
4. (3 + 4y)(5y - 1)
3(5y - 1) + 4y(5y - 1)
15y - 3 + 20y^2 - 4y
20y^2 + 11y - 3
5. (2n - 3p)(3p - 2m)
2n(3p - 2m) + -3p(3p - 2m)
6np - 4mn + -9p^2 + 6mp
-9p^2 - 4mn + 6mp + 6np
Hope this helps!
