Answer:
side of square is 2-x
Step-by-step explanation:
Area of the square is side * side or side ², so the expression for the side has to be square root of area
A = 4 -4x + x²
It should be recognized that 4 -4x + x²is a special product ( 2-x)² because this is a perfect square trinomial
side of square is 2-x
To find the surface area of the rectangular prism the area of all the sides must be found and added together.
The formula for the surface area of a rectangular prism can be expressed as:

where

= length

= height

= width
Before plugging in the values in the equation the length of the prism must be converted to inches
1 ft. = 12 in.
Therefore 2 ft. = 24 in.
By plugging in the values of length, width, and height into the equation
2(24)(14) + 2(24)(11) + 2(14)(11) = 1508 in.²
Answer:
Angle D= 140
Step-by-step explanation:
7x+7x+ 4x+4x+7x+7x= 720
36x=720
x= 20
When you say congruent the figures must be the same, not just the segments
when you say the segments have equal legnth, only the segments are compared
