- The value of x from the figure is 8
- The perimeter of AED is 30.80
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.

Let s = Car B's speed
Car B is 15 mph faster than A, therefore
(s - 15) = Car A's speed
Write a distance equation; dist = speed * time
2(s-15) = 1.5s
2s - 30 = 1.5s
2s - 1.5s = 30
.5s = 30
s = 60 mph is car B's speed
Confirm this find the distances, they should be equal
2 (60-15) = 90
1.5 (60) = 90
$0.15 because I added all and multiplied them then subtracted it by $3.00
Answer:
yes
Step-by-step explanation:
8/25= 0.32 which is a terminating decimal
