Answer:
-6
Step-by-step explanation:
x - 8 = -14
Add 8 to both sides of the equation
x - 8 + 8 = -14 + 8
x = -6
Answer:
12.6
Step-by-step explanation:
2 1/3 × 5 2/5
2 1/3= 7/3
5 2/5= 27/5
7/3×27/5= 12.6
You have to combine like terms.
Answer: -2a+7
Answer:
The length of the side PC is 34 cm.
Step-by-step explanation:
We are given that BP is the perpendicular bisector of AC. QC is the perpendicular bisector of BD. AB = BC = CD.
Suppose BP = 16 cm and AD = 90 cm.
As, it is given that AD = 90 cm and the three sides AB = BC = CD.
From the figure it is clear that AD = AB + BC + CD
So, AB =
= 30 cm
BC =
= 30 cm
CD =
= 30 cm
Since the triangle, BPC is a right-angled triangle as
PBC = 90°, so we can use Pythagoras theorem in this triangle to find the length of the side PC.
Now, the Pythagoras theorem states that;


= 1156
PC = 34 cm
Hence, the length of the side PC is 34 cm.
