no they are different
if Base are equal power are added
like wise in first expressions power are added
but in second expressions cube of three is written as x to the power.
so they are not equal
Answer:
78 inches
Step-by-step explanation:
perimeter of a kite formula: 2(a+b)
a= 18 inches
b= 21 inches
2(18+21)
2(39)
78 inches
A convex polygon
Hope this helps :)
Yo sup??
y=(x+4)(x-2)
to find the x intercept put y=0
0=(x+4)(x-2)
so either x=-4 or x=2
Therefore the graph intersects the x axis at -4 and 2
Lenght of x intercept=|-4-2|=6 units
y=(x+4)(x-2)
=x^2+2x-8
This is an upward opening parabola
To find the coordinates of the vertex we can apply the formula
(-b/2a,-D/4a)
b=2
a=1
D=b^2-4ac
=4-4*1*(-8)
=4+32=36
Vertex=(-2/2*1,-36/4*1)
=(-1,-9)
Hope this helps.
<em>x = 25</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
- <em><u>
the opposite angles are equal</u></em>
<em><u>4x - 25 = 25 + 2x</u></em>
<em><u>4x - 2x = 25 + 25</u></em>
<em><u>2x = 50</u></em>
<em><u>x = 50 : 2</u></em>
<em><u>x = 25</u></em>
<em><u>Good luck ! </u></em>
