When you lay them out then you know what you are dividing
Given the value of t3 and t7, and t7 = t3 * r^4, where r represents the geometric quotient.
So 7104 = 444 * r^4 -> solve for r, you will get r = 2 or -2
So, for r = 2, t6 = t7 / r = 7104 / 2 = 3552
For r = -2, t6 = -3552
8. ab = cd
.. 3x+4 = 4x-1
.. 5 = x
.. ab = 3*5 +4
.. ab = 19
11. Adjacent vertex angles are supplementary and opposite angles are equal. If the angles are vertex angles numbered in order around the figure,
.. ∠2 = 12°
.. ∠3 = 168°
13. If the quadrilateral is a parallelogram so that point E is the midpoint of both diagonals, it will be a rectangle when the diagonals are equal length.
.. ae = be
.. x +22 = 3x -18
.. 40 = 2x
.. x = 20 . . . . . will make segments AE and BE the same length

In general, diagrams are helpful for geometry problems.
Answer:
Step-by-step explanation:
58 cubic centimeter = 58 millimeter
Answer:
see explanation
Step-by-step explanation:
The perimeter is the length of all 6 sides of the polygon.
Note that the 2 unknown sides are
8 - 4 = 4 mm and 8 - 2 = 6 mm
Starting with the left side
Perimeter = 8 + 2 + 4 + 6 + 4 + 8 = 32 mm
The polygon can be split into 2 rectangles.
The lower rectangle with sides of 8 and 4
and the upper rectangle with sides 2 and 4
Area = (8 × 4) + (2 × 4) = 32 + 8 = 40 mm²
