Question

Help me please

Answer 1

it's an isosceles trapezoid which means that the two sides are equal: AB=CD
so set it as:
\(AB=CD\\\frac{1}{2}x+8=x-4\)
and solve for \(x\), then substitute it on the equation for \(AB=\frac{1}{2}x+8\)

Answer 2

what do i do first

Answer 3

collect like terms,
for example: 2a + 3= a -4, we collect the term which has the variable "a" and the terms without the variable
so it will become 2a-a = -4-3, simplifying it will become a=-7
did you get it?

Answer 4

no im sorry

Answer 5

i'll tell you what to do, step by step

from the equation above: \(\frac{1}{2}x+8=x−4\)
we collect the terms with variable "x"
to do that, subtract both sides by \(\frac{1}{2}x\)
can you do that for me?

Answer 6

wpu;d both sides be 8 n -4

Answer 7

\(\frac{1}{2}x+8- \Large{\frac{1}{2}x} = x-4 - \Large {\frac{1}{2}x} \)
\(\frac{1}{2}x\) on the left side will cancel out, next you need to simplify the right side//

Answer 8

woul it be 7.50?

Answer 9

did you work it out already?
i got a different answer though :/

Answer 10

oh i ment for the left side or is that not what im suppose to do?

Answer 11

how did you get 7.50?

Answer 12

i dont know. im so confused

Answer 13

let me show you then :)
