Use the distributive property to write the expression without parentheses.
7(4a +5)

28a + 35

Step-by-step explanation:

When you are using the distributive property, you need to multiply the number right outside of the paranethesis to both numbers. In this case, that number is 7. 4a and 5 are in the paranthesis, so we need to multiply 7 to 4a and 5. In the end, we get 28a and 35 or 28a + 35

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

where are the images of the functions i can only see the question you typed.
