Answer:
x ≈ - 6.49, x ≈ 12.49
Step-by-step explanation:
Given
(x - 3)² + 7 = 97 ( subtract 7 from both sides )
(x - 3)² = 90 ( take the square root of both sides )
x - 3 = ± 
( add 3 to both sides )
x = 3 ±
Then
x = 3 - ≈ - 6.49 ( to the nearest hundredth )
x = 3 + ≈ 12.49 ( to the nearest hundredth )
Answer:
a)7, b)-40
Step-by-step explanation:
a) 5(x-1)=30
=>5x -5=30
=>5x=30+5
=>5x=35
=>x=35/5
so, x=7
b)3(x+10)-2(x-5)=0
=>3x+30-2x+10=0
=>x+40=0
so,x=-40
