Write an equivalent expression for 20a + 24b

10a + 10a + 12a + 12a

hope this helps

have a good day :)

Step-by-step explanation:

2(5a+5) + 2(8b+4)

Step-by-step explanation: The 2 outside the parentheses gets distributed to the ones inside the parentheses. So 2 times 5a Is 10a plus 2 times 5 is 20a. Then the other one does the same, 2 times 8b is 16b plus 2 times 4 is 8 which makes 24b so 20a + 24b can also be 2(5a+5) + 2(8b+4)

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

probability for j is 1/4
