To get the value of x, we will use the similarity theorem of the triangle;
a) From the given image:
On factorizing
Since x cannot be negative, then x = 8
b) The perimeter of AED = AE + ED + AD
Given
AD = 10
ED = x = 8
AE² = AD² + ED²
AE² = 10²+8²
AE² = 100 + 64
AE² = 164
AE = √164
AE = 12.80
Perimeter of AED = 12.80 + 8 + 10
Perimeter of AED = 30.80
Hence the perimeter of AED is 30.80.

Answer:
option e
Step-by-step explanation:
2x^2-4x+9
use formula x=(-b+-root(b^2-4ac))/2a
4/3x -5
either, 2x =53
x=53-2=51
hence,3y=53
y=53-3=50
:x=51 & y=50
