Pls answer! i will mark brainliest!
Volgvan

Answer:

3 inches

Step-by-step explanation:

(14+2x) × (15+2x) = 2(14×15)

210 +30x +28x + 4x² = 420

4x² + 58x - 210 = 0

2x² + 29x - 105 = 0

2x² + 35x - 6x - 105 = 0

x(2x + 35) - 3(2x + 35) = 0

(x - 3)(2x + 35) = 0

x = 3, -35/2(not possible)

Find an equation of the tangent plane to the parametric surface x=−2rcosθ, y=−2rsinθ, z=r at the point (−22–√,−22–√,2) when r=2,
mojhsa [17]

The  equation of the tangent plane to the parametric surface is 3x + 2y + 6 root2z = 0.

A tangent to a curve was a line that just touched the curve at that point and was "parallel" to the curve at that point. A well-tangent plane to a surface is a plane that just touches the surface at that point and is "parallel" to the surface at that point.

The tangent plane to surface S at point P0 includes all tangents to curves in S that pass through P0. For a plane tangent to a surface to exist at a point on that surface, it is sufficient if the function defining the surface is differentiable at that point.

What is the solution to the system y>-2x+2 and y>-2x+5?
ELEN [110]

"y>-2x+2 and y>-2x+5" are illustrated graphically by 2 straight dashed lines with slope -2. The lines are parallel because their slopes (-2) are the same. One line has y intercept 2 and the other has y intercept 5. The latter is above the former. Since both inequality signs are " > " we must shade the area ABOVE each of the 2 lines. The solution set is the area of the graph that has been shaded twice, once for y>-2x+2 and again for y>-2x+5. It's y>-2x+5 that has been shaded twice; this area is immediately above the line y>-2x+5.
