What are the like terms in the expression below? 3mn – 4m + 2n + 7m – 5 a) 3, -4, 2, 7 & -5 b) 3mn, -4m, 2n, 7m c) 3mn, 2n d) -4m, 7m e) there are no like terms.

D. -4m, 7m

Step-by-step explanation:

Like terms are terms that can be added, subtracted, divided, and multiplied together. Since -4m and 7m both have the variable m, they are like terms. 3mn is not a like term because it has two variables which makes it different form -4m and 2n. It is its own term.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
