5(f + 4) = 4(f - 6) NEED HELP ASAP, ALSO PLEASE HELP ME DO IT STEP BY STEP!!

Step-by-step explanation:

5(f+4)=4(f-6)

5f+20=4f-24 : distribute the 5 and 4 to the equations in parentheses by multiplying

f+20=-24 : subtract the 4f from the right side and bring it to the left side where the 5f is

f=-44 : subtract the 20 from the left side and add it to the -24

it has changed from the width and the height.

step-by-step explanation:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
