Answer:
$16.
Step-by-step explanation:
Let t represent the cost of each tree.
We have been given that Yuri purchased 8 trees to have planted at his house. So the cost of 8 trees will be 8t.
We are also told that the store charged a delivery fee of $5 per tree. So the delivery charges of 8 trees will be 
The total cost of purchasing 8 trees will be
.
Since the total cost of the trees including the delivery was $168, so we can get an equation as:



Upon dividing both sides of our given equation by 8, we will get:
Therefore, the cost of each tree is $16.
The x² term will be C(5,2)x²·2³ = 80x².
The coefficient is 80.
_____
C(n, k) = n!/(k!·(n-k)!)
C(5, 2) = 5·4/(2·1) = 10
Answer:
arc of WXY= 224°
Step-by-step explanation:
measure of angle C is half of the WXY arc
this means WXY×1/2=C
112°=1/2 WXY (cross production)
WXY=2×112°
WXY=224 °
