solution:
Since, it’s a standard cone opening up on the positive x – axis therefore,
X = √y²+z²
And because it has a vertex at (7,0,0)
Therefore the equation of surface is
X = 7 + √y²+z²
The answer is x+5
you have to combine like terms:
2x+5-x
Combine the x's
2x-x= x
Since there is nothing left the answer is
x+5
X=8
Explanation:
f(x)=x^2-16x+64+(x-8)^2
You see there is a double x- intercept by the 8. So the parabola is tangent to the x axis. So x=8 f(x)=0

Answer: You would get 1 for the first section
Step-by-step explanation: you square whatever number is the x then you cube the x.
Answer:
a) m∠3=113°
b) x=8 (but check below)
Step-by-step explanation:
a) we know m∠1=m∠5
6x-5=5x+7
x=12
we also know m∠1+m∠3=180°
plug x into the formula for m∠1
m∠1=67
m∠1+m∠3=180°
67+m∠3=180°
m∠3=113°
b) Again, we know since those lines are parallel that m∠4=m∠8
x²-4x=32
x²-4x-32=0
(x-8)(x+4)=0
x=8 or x=-4
i think (not 100% sure about this part lol) but x cannot be negative so it's 8
again i'm not sure but it is either 8 or 8,-4.
