For this case we have that by definition, the area of a rectangle is given by:
Where:
w: Is the width of the rectangle
l: is the length of the rectangle
According to the data of the statement we have:
Substituting:
Substituting the values:
Thus, we have two roots:
w_ {1} = \ frac {5+ \ sqrt {157} {2}} = 8.77
w_ {2} = \ frac {5+ \ sqrt {157} {2}} = - 3.77
We choose the positive value. So the width of the rectangle is approximately 8.77 meters and the length is 3.77 meters
Answer:
Answer:
Step-by-step explanation:
Vertex-form equation for vertical parabola:
y = a(x-h)² + k
with
vertex (h,k)
axis of symmetry: x = h
Apply your equation
y = 3x² + 18
vertex (0,18)
axis of symmetry: x = 0
Answer:
Use photo math, it will explain all the steps
Answer:
20%
Step-by-step explanation:
(61200-51000)/51000×100
(102000/51000)×100
0.2×100=20%
Hope that helped! :)
For me I will pick equation 1 because you get a whole number 1(2x-3)+5=4 so you multiply 1•2x and 1•-3,+5=4
So is going to be 2x-3+5=4 so you will add -3+5 and it will equal 2 them you will subtract 2 from 4 then you divide it by 2x and your x=1 that's your answer
