x = 5i x =-5i
Step-by-step explanation:
x^2+25=0
Rewriting
x^2 - (-25)=0
Writing as the difference of squares
a^2 - b^2= (a-b) (a+b)
where a = x and b = (sqrt(-25)) =±5i
( x-5i) ( x+5i) =0
Using the zero product property
x-5i =0 x+5i =0
x = 5i x =-5i

Answer:
144ft^2
Step-by-step explanation:
since it's a kite, there are two pairs of congruent (exactly the same shape) triangles
bc of this you can find one triangle from each pair and double it
e.g.


so you would do 2(24+48)=144
Answer:
<ECF = 45 degrees
Step-by-step explanation:
If ABCD is a square, then the diagonal AC divides angle <C and angle <A in two equal parts. Angles A and C are also 90 degrees each due to the act that the figure is a square. Therefore their bisection would render 90/2 = 45 degrees.
Notice as well that angle <ECF is opposite by the vertex to one of these 45 degree angles, and then it must measure the same amount (45 degrees).
So, <ECF = 45 degrees
Answer:
¼
Step-by-step explanation:
20 ÷ 80 = 0.25
0.25 = ¼ or 1 quarter
