First you want to subtract 36
so it looks like this ![\sqrt[4] {(4x+164)^3}=64](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%20%7B%284x%2B164%29%5E3%7D%3D64)
Then you want to cancel out the square root 4 by raising that to the 4th power (you must do this to both sides)
which is equal to 
Then you take the cube root to both sides [tex]\sqrt[3]{(4x+164)^3}=\sqrt[3]{16777216}[tex]
Then you end up with the equation 4x+164=256
Then subtract 164 to both sides
4x=92
then divide 92 by 4
Then you get x=23
Answer:
2(x-3)(x+2)
Step-by-step explanation:
2x^2 - 2x - 12
2(x^2 - x -6)
2(x^2 - 3x + 2x - 6)
2(x(x - 3) + 2(x - 3))
2(x-3)(x+2)
Answer:
Step-by-step explanation:
To find the x-intercept, substitute 0 for y and solve for x:
Divide both sides by 2:
Add 7 to both sides to isolate x:
The x-intercept for 
is 7 at point 
.
Remove parentheses:
Subtract 2 from both sides:
The x-intercept for 
is -2 at point 
.
Finito.
Answer:
∠A=30°
Step-by-step explanation:
let's call the angle at the bottom B and the one next to the 130 C
∠A=3x-6
∠C=180-130= 50°
vertical angles are equal∠B =8x+4
∠A+∠C+∠B=180°
find x:
3x-6+50+8x+4= 180°
11x+48=180°
11x= 132
x=12
find ∠A
∠A=3x-6= 3(12)-6 =30°
There are enough information's already given in the question. Based on those information's that answer can be easily deduced.
Radius of the sphere = 8 units
Then
Surface area of the sphere = 4 *pi * r^2
= 4 * pi * (8)^2
= 4 * pi * 64
= 256pi
I hope that this answer has come to your help.
