Eamon uses the greatest common factor and the distributive property to rewrite this sum: 28 + 42 which expression does eamon write? a. 7(4+6) b. 14(2+3 c.21(1+2) d.28(1+2

B) 14(2+3)

14 is the greatest common factor, it can be divided by two numbers, 7 and 2

option A, 7 is the least common factor it can only be divided once by 7 so although A = 70 it isn't the greatest common factor

Now to check if B is correct

Use order of operations to solve P E M D A S

2+3 = 5

14(5)

Multiply

70, Answer is 70 as his sum.

B is correct

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48

step-by-step explanation:

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.
