Answer 1

@Arcadiouse Can you help with this?

Answer 2

I am currently helping one in Science but I can attempt in a bit I guess.

Answer 3

I don't mind.

Answer 4

you know this ?

Answer 5

Yeah, I have somewhat of an understanding, I am working on science problems and your problem at the same time, so give me a minute and I can help.

Answer 6

Part A: Rational, Rational. That is what I got.

Answer 7

Part B both are also rational. I swear this was easy but its odd that all four answers are rational.

Answer 8

are you sure ?

Answer 9

I did my math multiple times, hold on ill do it again.

Answer 10

Haha, Im wrong.

Answer 11

Sorry dude, I would wait for @Vocaloid he does this type better than me. I have't done this math in forever.

Answer 12

do you know where vocaloid at ?

Answer 13

For the love of... You guys know vocaloid is female right?

Answer 14

no

Answer 15

The area, A, of a trapezoid-shaped garden is given by the equation A = 1/2w(b + c)


Hector knows the area of the garden, the width (w), and the length of one of the parallel sides (b). He wants to find the length of the other parallel side, c.

Which of these shows the equation to find the length of the other parallel side, c?

A. c = A/2w - b

B. c = 2A/w - b

C. c = 2A/bw

D. c = A/2bw

Answer 16

Well now you do.

Answer 17

I didn't.

Answer 18

I DIDN'T KNOW

Answer 19

Oh good Sam is viewing the question, @Sam any chance you can help them? x'D

Answer 20

Yeah, I kinda forgot some of this. So I tried my best then realized I had my irrationals and rationals mixed up :(.

Answer 21

And this is why I tend to stay out of math unless its math i ace lol.

Answer 22

Oh wait you don't have to solve a trapezoid, you just have to mess around with the equation given

Answer 23

You've got
\[A = \frac{1}{2}w(b + c)\]
So arranging this equation
First multiply both sides by 2,
\[2A=w(b+c)\]
Divide both sides by w,
\[\frac{2A}{w}=b+c\]
Minus both sides by b and there's your c isolated

Answer 24

so it's B ?
