Use the distributive property to solve the expression. show all work! 4(a + 8)

In order to do this like they tell you you have to do distributive property, you do this by multiplying the outside number with the insides number or variables to get your full answer. First we will multiply 4 times a to get 4a and then you will multiply 4 times 8 to get 32 This means your answer is 4a+32

Hope this helps

Distributive property
a(b+c)=ab+ac
4(a+8)=4(a)+4(8)=4a+32

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
