Answer: 132 cm²
-----------------------------------------
To find length and width you need to factor 3x² - 10x - 8. The final factored form will be (3x+2)(x-4).

Answer:
16. x = 11
17. x = 4
Step-by-step explanation:
The triangles of interest are congruent, so corresponding parts have the same measure.
__
16. 2x+2 = x+13
x = 11 . . . . . . . . . subtract x+2 from both sides
__
17. 4x+4 = 3x+8
x = 4 . . . . . . . . . subtract 3x+4 from both sides
Answer: Yes, she could be considered similar to herself at 6 months of age.
In mathematics, the concept of similarity is about proportion relationships. In this problem, we are discussing the relationships between age, height and diameter. We are not discussing the absolute value of the numbers themselves.
For example in Geometry, a very small triangle can be similar to a very large triangle if all the angles of the triangle are congruent. The size doesn't matter.
