Answer:
x = -5
Step-by-step explanation:
-9(x+3) = -9x-27
Add 27 onto both sides and get -9x = 45
Divide -9 on both sides and you'll see that x = -5 because 45/-9
Answer:
ZD = 10
Step-by-step explanation:
In a parallelogram
- Every two opposite sides are parallel
- Every two opposite sides are equal
- Every two opposite angles are equal
- Every two adjacent angles are supplementary
- The two diagonals bisect each other (meet each other at their midpoint)
Let us solve the question
∵ ABCD is a parallelogram
∵ AC and DB are its diagonals
→ By using the 5th property above
∴ AC and BD bisect each other
∵ AC ∩ BD at point Z
→ That means Z is the midpoint of them
∴ Z is the midpoint of BD
→ That means Z divides BD into 2 equal parts BZ and ZD
∴ BZ = ZD
∵ BZ = 10
∴ ZD = 10
Answer:
the value of expression is 19
Step-by-step explanation:
here's the solution :-
if x = 10 ,
let's replace the value of x with 10
=》x + 9
=》10 + 9
( since, x = 10 )
=》19
