Answer:
y=14
Step-by-step explanation:
We are told that the legs of the isosceles trapezoid are AB and CD
AB = 7y - 4
CD = 8y - 18
In any isosceles trapezoid, the two legs are of equal length.
Therefore, AB = CD
⇒ 7y - 4 = 8y - 18
Add 18 to both sides of the equation
7y - 4 + 18 = 8y - 18 + 18
7y + 14 = 8y
If you are trying to simplify then you would have to combine like terms
3kgx296g+5kg+326g (there is no sign between 3kg and 296 so i am assuming that is multiplied)
add 3kg+5kg and get 8kg
add 296g+326g and get 622g
So the equation would be 8kg*622g
Hope this helped!! :D

Answer:
9cm
Step-by-step explanation:
The CIRCUMFERENCE OF A CIRCLE is the distance round the circle.
It has the formular 2πr.
were r = radius
C = 2πr
72 = 2 × 3.142 × r
72 = 6.284r
dividing bothsides by 6.284
r = 72/ 6.284
r = 11.457
AB is an arc.
Lenght of an arc
