Answer: B?
Step-by-step explanation:
Since it already shows it in feet, you can multiply 18 by 16.
-288
And because it is $4.50 per square root, you can multiply 4.50 by 288 and you get 1,296.
(I don't really know tho..)

Step-by-step explanation:
Answer:
7
Step-by-step explanation:
The diagonal is the hypotenuse of the right triangle with legs 7
Use Pythagoras' identity to solve for the diagonal d
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
d² = (7)² + (7)²
= 147 + 147
= 294 ( take the square root of both sides )
d = 
= 7 ≈ 45.37 ( to 2 dec. places )
Polygons, Number of sides, Measure is angles, and angle sums
Answer:
A. 3m² + 4m + 1 = 0
3m² + 3m + m + 1 = 0
3m (m + 1) + 1 (m + 1) = 0
( 3m + 1 ) (m + 1) = 0
B. 16n - 25
16n = 25
n = 25/16
