I think what you meant was
(2x - 5)² = 11 -- (1)
Square root both sides of (1), i.e.
√(2x - 5)² = ± √11 -- (2)
From (2), we have
2x - 5 = ± √11 -- (3)
By adding 5 to both sides in (3), we have
2x = 5 ± √11 -- (4)
Divide both sides of (4) by 2, and we obtain
x = (5 ± √11)/2 -- (5)
From (5), the solution set of (1) is
x = (5 + √11)/2, (5 - √11)/2 ...Ans.
Answer:
155.25= 12
Step-by-step explanation:
17/2*2*1/2 = 12
17*1/2 = 12
8 1/2 17/1* 1/2
8*2+1 17*1/1*2
2 17*1/1*2
16+1 17/1*2
2 17/2

Answer:
42
Step-by-step explanation:
HIJK IS increased by a factor of 3/4 to formH'I'J'K'
so every side is increased by a factor of 3/4
so,Side J'K'=24+24×3/4=42
