Answer:
29
Step-by-step explanation:
First, replace v with 6 and k with 12
12/6 + 5 - 4(6) + 12
12/6= 2
2 + 5 - 4(6) + 12
4(6) = 24
2 + 5 - 24 + 12
2+ 5 = 7
24 + 12 = 36
7 - 36 = 29
hope this helps!
Answer:
there is no picture added
Step-by-step explanation:
The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola. The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
Answer:
The width is 5m and the length is 10m.
Step-by-step explanation:
Rectangle:
Has two dimensions: Width(w) and length(l).
It's area is:
The length of a rectangle is 5m less than three times the width
This means that 
The area of the rectangle is 50m^(2)
This means that 
. So
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots 
such that 
, given by the following formulas:
In this question:
So
Dimension must be positive result, so
The width is 5m(in meters because the area is in square meters).
Length:
The length is 10 meters
We need to create an equation in order to solve this problem.
Let x = the smallest number
x+1 = next number
x+2 the following number
x+3
x+4
x+5
x+6
So, we add those.
x+x+1+x+2+x+3+x+4+x+5+x+6=105
7x+21=105
7x = 84
x = 12
So the numbers are
12,13,14,15,16,17,18
