Answer:
2)
(2x -5) + (x) + (2x - 3) = 32.
5x-8 = 32.
ii) 5x-8=32
5x= 32+8
5x = 40
x= 40/5
x = 8
iii) 2x -5
2 × 8 -5 = 11.
2x-3
2×8-3
16-3 = 13
x =8
sides of the triangle= 8, 11, 13.
Answer:
Step-by-step explanation:
x²-px-p-c=0
sum of roots=α+β=-b/a=p
product of roots=αβ=c/a=-p-c
(α+1)(β+1)=αβ+α+β+1=-p-c+p+1=-c+1
Answer:
The first one, all quadrilaterals have at least 1 pair of parallel sides
