Maria ran farther. Tyler did more. hopefully this helps
To answer this question we will have to keep the following two points in mind:
#1. The <u>sum</u> of a number with another number means to <u>add </u>the given two numbers.
#2.<u> Twice</u> means to <u>multiply by 2.</u> In other words it means to double.
Therefore, "twice the sum" would mean to multiply the sum by 2.
Now, in our question we will have, "the sum of y and 9 would be: 
and twice this sum would be: 
Thus, "twice the sum of y and 9" is:
Answer:
10yd
Step-by-step explanation:
area= 1/2bh
area=32yd²
b= 6.4, ¹/2b=3.2
therefore, 32= 3.2h
h= 32/3.2
= 10yd
Answer:
An apothem is a line drawn from the centerpoint of the polygon to one side of the polygon. There is a formula for area in terms of apothem:
A = (1/2)*(Perimeter)*(Apothem)
The perimeter of the regular polygon is just the length of one side multiplied with the number of sides. Since a polygon with 9 sides,
P = 9(15) = 135in
A = 1/2 ×135 × 12
A = 810 square inches ans
