We have the formula for the area of a triangle equal to A=l*w, where stands for the area, l for the length and w for the width. Given in the problem are the following:
A=135 m
l=6+w
w=w
Solving for the value of w, we have:
A=(w+6)*w
135=w²+6w
w=9 meters
Therefore, the length of the rectangle is 15 meters.
Answer:
B. x=1+2i or x=1-2i.
Step-by-step explanation:
The equation is given as;
x²-2x+5=0
complete the square method to find value of x as;
x²-2x = -5
x²-2x + 1 = -5 + 1
x²-2x +1 =-4
( x-1 )² = -4
x-1 = ±√-4 ---------<em>where √-1 = i</em>
x-1 =± 2i
So;
x-1 = + 2i
x= 1+2i
or
x= 1-2i
x= 1-2i
-10x. All you have to do is subtract -2 from -8 and then put an x there so it’s -10x
