Answer: 7\ \text{mm}^2

Step-by-step explanation:

Given : A slice is made parallel to the base of a right rectangular pyramid.

The part of the larger rectangle that intersects the pyramid is a smaller gray rectangle.

i.e. the resulting two-dimensional cross-section is represented  by smaller gray rectangle.

The front side of the smaller rectangle is labeled 3.5 millimeters, and the right side is labeled 2 millimeters.

Then, the area of the resulting two-dimensional cross-section = 3.5\times2=7\ \text{mm}^2

Help please and help me understand how to solve
natulia [17]

Answer:

Step-by-step explanation:

You have a right triangle here.  The way to solve for a missing side in a right triangle is to use Pythagorean's Theorem.  You can't use right triangle trig because you don't have an angle. Pythagorean's Theorem is, in this case,

x^2=6^2+(2\sqrt{3})^2 and

x^2=36+12 and

x^2=48 so

x=\sqrt{48} which simplifies down to

x=4\sqrt{3}

Find the distance between the two points. (−4, 7), (4, 0)
MA_775_DIABLO [31]

Distance²  =  (difference in 'y')² + (difference in 'x')²

                =                 (0 - 7)²  +  (4 + 4)²

               =                    49       +      64

               =                     113

Distance =        √113  =  approx. 10.63   (rounded)
