The sides of this triangle are 5x,6x abd 7x,
The perimeter of a triangle is the sum of all sides
We can suggest this inequation:
5x+6x+7x<54
18x<54
x<54/18
x<3
Therefore the lenght of the longest side would be:
7x<(7*3)
7x<21
Answer: the lenght of the longest side would be <21
Answer:
Step-by-step explanation:
To find the intercept with the x axis, we make h (x) = 0.
0 = (x + 1) ^ 2 - 4
0 = x ^ 2 + 2x + 1 -4
0 = x ^ 2 + 2x - 3
0 = (x +3) (x-1)
x = 1
x = -3
To find the intercept with the y axis, we make x = 0.
y = (0+1)^2 -4
y = -3
For a quadratic equation of the form ax ^2 + bx+ c
The vertex is calculated with the formula x = -b/2a
So:
x = -2/2(1)
x = -1
Finally the axis of symmetry of a quadratic function always passes through the vertex.
So:
x = -1
Below is a graph for this function, where you can see the cut points with the axes, the vertex and axis of symmetry
Answer:

Step-by-step explanation:
Given
Distance XY is calculated as thus:
Distance ZW is calculated as thus:
<em>Hence:</em>
<em>XY and ZW are congruent</em>
Answer:
the simplest form is just the simplest a number can be, or least complicated, for example,
2^2 +2 -5 is a lot bigger than it needs to be, so if you simplify it to the simplest form by doing all these small equations, you would get, 1.
