Answer:
Step-by-step explanation:
2x to the power of 2 + x = ? When x=9
(2x)^2 + x
= 4x^2 + x
When x = 9
= 4(9)^2 + 9
= 4(81) + 9
= 324 + 9
= 333
There are 8 gallons in 32 quarts becuase 4 quarts = 1 gallon so 32 divided by 4 is 8. Hope this helped! :)

bisects
Given
2.
Definition of angle bisector
3.
Reflexive property
4.
bisects
Given
5.
Definition of angle bisector
6.
ASA postulate
Q13.
1. Consider triangles ACB and DCE. In these triangles,
- given;
- given;
- as vertical angles (by vertical angles theorem)
Hence, triangles ACB and DCE are congruent by SAS postulate.
2. congruent triangles have congruent corresponding sides, so

3in x 5 sides = 15in
perimeter = 15in
