Answer and explanation:
Surface area of a rectangle = length * width
Surface area of a square = a² where a is length of a side
To find total surface area of the the five pieces of paper, we add up all the areas of all the shapes
Given that length of rectangle =3.5
And width = 2
Area of rectangle =3.5*2=7
Area of 3 rectangles given they are all equal = 7*3=21
Since width of rectangle equal to width of square and all sides of square are equal
Area of square = 2 *2 =4
Area of the two squares =4*2=8
Total surface area of the five plane shapes = 21+8= 29

Answer:
x=17/13
Step-by-step explanation:
-3(3x-3)=4/5(5x-10)
-9x+9=4x-8
-13x= -17
x=17/13
Answer:
96
Step-by-step explanation:
180-84=96
Answer:
A
Step-by-step explanation:
n=-7m-4
14m+2n=-8
Substitute the first equation into the second one/
14m + 2(-7m - 4) = - 8
14m - 14m - 8 = - 8
- 8 = - 8
This means than m can be anything, and therefore there are an infinite number of possible answers.
A
