Question

Do This
1. Find the sum of the like terms.
(i) 5x, 7x
(ii) 7x’y, -6xy
(iii) 2m, 11m
(iv) 18ab,5ab, 12ab
(v) 3x?, -7x?, 8x2
(vi) 4m2, 3m2, -6m², m2
(vii) 18pq, -15pq, 3p


2. Subtract the first term from the second term.
(i) 2xy, 7.xy
(ii) 5a, 10a
(iii) 12y,3y
(iv) 6x?y, 4xy
(v) 6xy, -12xy​

Answer 1

Answer:

pl check the qstns which I marked not possible

Step-by-step explanation:

1] i)5x+7x=12x

ii)not possible

iii)2m+11m=13m

iv)18ab+5ab+12ab=35ab

v)not possible

vi)4m²+3m²-6m²+m²=2m²

vii)18pq-15pq+3pq=6pq

2] i)7xy-2xy=5xy

ii)10a-5a=5a

iii)3y-12y=-9y

iv)not possible

v)-12xy-6xy=-18xy
