Step-by-step explanation:
Step1=8x-6=2(6+2x+2)
Step2=8x-6=12+4x+4
Step3=8x-6=16+4x
Step4=4x=20
Step5=x=20÷4
Step6=x=5//Ans
Step-by-step explanation:
∫ 15 ln(x) dx / (x √(6 + (ln(x))²))
Substitute: If u = ln(x), then du = 1/x dx.
∫ 15 u du / √(6 + u²)
Substitute again: If v = 6 + u², then dv = 2u du.
∫ 15/2 dv / √v
15/2 ∫ v^-½ dv
15 v^½ + C
15√v + C
15√(6 + u²) + C
15√(6 + (ln(x))²) + C
Area of circle= pi (3.14) times by radius (half of diameter) squared So: 19.6 cm squared
Answer:-1
Step-by-step explanation:
2(3x-4)+x-1=-16
Open brackets
6x-8+x-1=-16
Collect like terms
6x+x=-16+1+8
7x=-7
Divide both sides by 7
7x ➗ 7=-7 ➗ 7
x=-1
Answer:
When x=−4\5 and y=1\3 we get x+y = -7/15
Step-by-step explanation:
We are given :
x=−4\5 and y=1\3
We need to evaluate : x+y
Solving:
Taking LCM of denominators 5 and 3, we get 15
So, when x=−4\5 and y=1\3 we get x+y = -7/15
