1) x+23=2x+8
x-2x= 8-23

-x = -15
x=15

2)x+23=2x+8
x-2x=8-23
x= 15

WU= UW= x+23=15+23= 38

3)UV=UW+WV

UV= x+23 + 2x+8

UV=15+23+2*15+8

UV=38+38

UV=76

4) YA=YZ+ ZA

YA= x+12 +6x -13

YA=7x -1

x=15

YA=7*15-1

YA=105-1

YA=104

Answer:

( 6(x)² + 12(x) - 90 ) ft³

Explanation:

  • <u>deep end water</u>: 2(x)² + 12(x) + 10
  • <u>shallow end water</u>: 4(x)² - 100

addition problem: 2(x)² + 12(x) + 10 + 4(x)² - 100

total volume of water:

  • 2(x)² + 12(x) + 10 + 4(x)² - 100
  • 2(x)² + 4(x)² + 12(x) + 10 - 100
  • 6(x)² + 12(x) - 90

Arte-miy333 [17]
The question is incorrect
the correct question is
A local citizen wants to fence a rectangular community garden. The length of the garden should be at least 110 ft,and the distance around should be no more than 380 ft. Write a system of inequality that model the possible dimensions of he garden. Graph the system to show all possible solutions

let
x---------------> t<span>he length of the garden
</span>y---------------> the wide of the garden

we know that
x>=110
2x+2y <=380---------------> x+y <= 190

Part A) <span>Write a system of inequality that model the possible dimensions of he garden
</span>
the answer part A) is
x>=110
x+y <= 190


Part B) <span>Graph the system to show all possible solutions

using a graph tool
see the attached figure
the solution is the triangle show in the figure

</span><span>the possible solutions of y (wide) would be between 0 and 80 ft
</span>the possible solutions of x (length) would be between 110 ft and 190 ft
