Step-by-step explanation below.
Answer:
Given that in a walking competition, Marlinda was 15m ahead of Sandra Evliani, and Marlinda steps 1m each time Sandra Elviani's foot steps 0.8m, to determine how many steps does Sandra Elviani have to make to match Marlinda, the following calculation must be performed:
Since Sandra Elviani walks 0.8 meters for every 1 meter that Marlinda walks, and that she has an advantage of 15 meters in the competition, it is impossible that at that rate Sandra can reach her. This is so because for each step of Marlinda, Sandra will be 0.2 meters behind her, increasing the distance (1-0.8).
You are basically trying to find the area of two triangles and a rectangle.
Rectangle= A= length*width
Triangle= A= 1/2*base*height
Rectangle:
1.5*1.9= 2.85
Two triangles:
A= 1/2* 0.5*1.5
A=1/2*.75
A=0.375
Multiply that by two, because the triangles are the same.
.75
.75+2.85= 3.6
3.60 ft^2 <== the answer :)

Step by step solution :
Step 1 :
Equation at the end of step 1 :
x + ((((3•19x2) • x6) • x8) • x12)
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
57x28 + x = x • (57x27 + 1)
Trying to factor as a Sum of Cubes :
3.2 Factoring: 57x27 + 1
Theory : A sum of two perfect cubes, a3 + b3 can be factored into :
(a+b) • (a2-ab+b2)
Proof : (a+b) • (a2-ab+b2) =
a3-a2b+ab2+ba2-b2a+b3 =
a3+(a2b-ba2)+(ab2-b2a)+b3=
a3+0+0+b3=
a3+b3
Check : 57 is not a cube !!
Final result :
x • (57x27 + 1)

I think it’s a reciprocal function
