Question

File attached, can someone help me solve this?

Answer 1

I can't open file

Answer 2

its a word document

Answer 3

Area a =(2x+5)*(x-2)+2x)

Answer 4

Area of A=(2x+5)(2x+x-2)=(2x+5)(3x-2)
=6x^2-4x+15x-10
=6x^2+11x-10

Answer 5

u want A an B ?

Answer 6

C) area for all shaded area = add two areas that you founded above together

Answer 7

area B = (2x)*(2x-7)

Answer 8

How is the Area of A (2x+5)^2?

Answer 9

and what would all the area's equal? Area A + Area B?

Answer 10

Area=length times width. You're multiplying length times length

Answer 11

all shaded areas= add two areas together

Answer 12

so (2x+5)^2+2x(2x-7) ?

Answer 13

@GS it should be 6x^2+11x-10 + 2x(2x-7)

Answer 14

oh ok, thanks. and for the last when it says check your work, and x=6. just plug it in?

Answer 15

Area A: (2x+5)(2x+x-2)=(2x+5)(2x-2)=272 (when x=6)
Area B: 2x(2x-7)=60
both areas= 332 (!)
I was wrong before... sorry!

Answer 16

k I'm so confused now LOL

Answer 17

what is confusing?

Answer 18

Well for the very last question, you plug in 6 for x. area A and area B at the end have to different answers, their both supposed to add up to the same number.

Answer 19

inik has the right answer now, he just got messed up with the area was all

Answer 20

Your answer for the last one should be 332 just like inik stated.

Answer 21

ok sorry, I get it, I was confusing myself with a different concept aha. Thanks guys! (:

Answer 22

this is your questions:
D. When x = 6, the total area of the shaded portion of the diagram is 332 square units. Use x = 6 to verify your answer from part (c) above

if you substitute x=6 in area for A & B & ADD them together you should have 332 & you do

Answer 23

ok sorry, I get it, I was confusing myself with a different concept aha. Thanks guys! (:

Answer 24

Great!!
