Can anyone help me with this math problem?

I’ve spent like the past 5 minues trying to work out how to multiply it out.

3(8+f) +(4+f)

I get the first bit, but I don’t understand how to multiply the second bracket because there is no number to multiply it by.

Answer #1

if you just simplify it its… 28+4f because its an expression not an equation because no = sign

Answer #2

Sorry, but like I’d ask my parents but they were out :( And I like to get full marks :)

Answer #3

I didnt say stupid, but I dont see bragging about things as good when you clearly didnt answer anything ( no offense intended, im just that kinda person)

Answer #4

you didnt exactly simplify anything, you just kinda I dunno repeated the first step, also its clearly an equation, f could as well be x (as in x = unknown) and generally these equations need solving and not simplifying

Answer #5

O_O its clear that its an equation, your 99 in geometry seems to have been a 9.9… all equations are equal to 0 unless otherwise specified

Answer #6

24+3f+4+f

Do it that way =) You can get the rest.

Answer #7

Dont assume it equals zero, sometimes they just want you to simplify (which is what it looks like here).

And “I get the first bit, but I don’t understand how to multiply the second bracket because there is no number to multiply it by.”

If there’s no number it is automatically a 1 so

3(8+f) +(4+f) = 3(8+f) +1(4+f) = 24 + 3f + 4 + f = 28 + 4f or 4 (7 + f)

Answer #8

:)

Answer #9

24+3f +(4+f) = 0 3f+f = -24-4 <–move all nmbrs to one side and all unknowns to the other 4f = -28 f = -7 Proof : 3(8+(-7) ) + (4 + (-7)) = 0 3(8-7) + (4 - 7) = 0 3 (1) + (-3) = o 3-3 = 0

I think this is the way

Answer #10

sorry, but this is not a site for homework help. I will not answer this question, although I know and nobody else should neither.

Answer #11

thank you soo much :D

Answer #12

24+3f+4+f=? The answer is= 76.
