Answer:
b Square
Step-by-step explanation:
I literally just counted
X=3
Y=5
0.30 x 5 = 1.5
1.50 x 3 = 4.5
1.5 + 4.5 = 6
In each case divide the price by the number of cans.
The best buy is the lowest price.
$12.53/7 = $1.79
$5.97/3 = $1.99
$7.95/5 = $1.59
$8.34/6 = $1.39
The fourth ad, $8.34 for 6 cans results in the lowest price per can, $1.39.
The fourth ad is the best buy.
Knowing that the angles of the triangle has a total of 180 degrees, so we can have the following:
x + y + z = 180
y + z = 180 - x
or
x = 180 - y - z
In this approach, we can't give the actual values since there are no values presented.
(x + 11) *squared* +(y-12) *squared* = 49
