Step-by-step explanation:
Put 4 where y is in the equation and do the arithmetic.

A) $55.00
65 yards for $85.00 subtract
20 yards for $30.00
85-30=55
Answer:

Step-by-step explanation:
It is given that,
Magnitude of a A, 
magnitude of B, 
The angle betwern a and b is 
Dot product,

So, a.b is equal to 0.
The mean is 23.875. That would be roughly $24 each time
Answer:
A = 140 in²
Step-by-step explanation:
The area (A) of the triangle is calculated as
A =
bh ( b is the base and h the perpendicular height )
here b = 20 and h = 14 , then
A =
× 20 × 14 = 10 × 14 = 140 in²
