Hey, it’s very easy. You just need to do like that:
z-2z-3=-7
z-2z= -7+3
-1z = -4 | : (-1)
z = 4
The answer is 4.
The answer is C. The easiest way to find this is by setting the top two angles added together to 180 because they divide a straight line. The just plug the numbers in and you get C

Equation of curves
Both curves lie on S.
We have to find the equation of tangent plane at P(4,1,4).
Hence, t=0 and u then it satisfied the given point.
Substitute the values in the derivatives
The equation of tangent at point P(4,1,4) is given by
Complete question :
A 12-foot by 15-foot patio is increased by placing a stone border around the patio. The width of the border is the same all around the patio.The perimeter of the patio after it is expanded is 74 feet. The equation which represents x, the width of the border is 2[(12+2x)+15+2x)]=74. What is the width of the border?
1) 2 1/2 feet
2) 3 feet
4) 5 feet
5) 8 1/2 feet
Answer:
2.5
Step-by-step explanation:
Solving for X in the perimeter equation :
2[(12+2x)+15+2x)]=74
Open the bracket
2[(12 + 2x + 15 + 2x)] = 74
2(27 + 4x) = 74
54 + 8x = 74
8x = 74 - 54
8x = 20
x = 20/8
x = 2.5
Hence, width fo border = 2.5
