Answer:
x=-4
Step-by-step explanation:
(x+4) ^ (1/3) + (2x+8) ^ (1/3) = 0
Subtract (x+4) ^ (1/3) from each side
(x+4) ^ (1/3) - (x+4) ^ (1/3)+ (2x+8) ^ (1/3) = -(x+4) ^ (1/3)
(2x+8) ^ (1/3) = -(x+4) ^ (1/3)
Cube each side
(2x+8) ^ (1/3) ^3= -(x+4) ^ (1/3)^3
2x+8 = -(x+4)
Distribute the negative sign
2x+8 = -x -4
Add x to each side
2x+8 +x =-x+x-4
3x+8 = -4
Subtract 8 from each side
3x+8-8 =-4-8
3x =-12
Divide by 3
3x/3 = -12/3
x = -4
The answer is 64!
hope this helps youu!!
Area is base x height
12 x 6 = 72
the area is 72 in^2
Since you already know BC is 23inches, you can minus it from 83 inches first.
Next, you have to realise that since angle ABC and angle ACB are both 65 degrees and equal, the triangle is an isosceles triangle it means that AC is equals to BC.
Thus, it means that you can divide (83-23) by 2, which is 30 inches
Answer:
The answer to your question is: y = -3x + 14
Step-by-step explanation:
Data
A (4, 2)
y = x/3 - 1
Perpendicular
original slope = 1/3
perpendicular slope = -3
Equation (y - y1) = m(x - x1)
(y - 2) = -3(x - 4)
y - 2 = -3x + 12
y = -3x + 12 + 2
y = -3x + 14
