Question

Can anyone help?- I need it by 11:30.

Answer 1

See Below

Explanation:

5.
`3.1 + (8.6 + m)\\3.1 + 8.6 + m\\11.7 + m`

take expression out of brackets by distribution (multiplying both by 1), then add

6.
`(((2)/(3))(t)) (1(1)/(2))\\((2)/(3)t) (1(1)/(2))\\((2)/(3)t) ((3)/(2))\\(6)/(6) t\\t`

Simplify the expression in the brackets by multiplying them together, once done turn the mixed fraction back into improper fraction in order to multiply the two together. Once done, simplify the expression

7.
`4(x + 8)\\4x + 32`

I would argue that factored form is the most simplified but regardless using the distribution rule you multiply both numbers within the bracket in order to get rid of it

8.
`4t + 7 + 2t - 2\\6t + 5`

This is just combining like terms and simplifying
