Answer:
(b) (x-3)(x+4)-18 = (x+6)(x-5)
Step-by-step explanation:
Here , the given expression is P(x) = (x-3)(x+4)-18
Simplifying the given expression ,we get:
So,the given polynomial P(x) can also be written as (x+6)(x-5)
Hence, P(x) = (x-3)(x+4)-18 = (x+6)(x-5)
Perimeter (P) of a square = 4s ; where s is the length of a side
1 yd = 4s
yd = s
Area (A) of a square = s²
= ()²
Now, convert from yard to foot to inch:
()² x (
)² x (
)²
= (3 x 3 x 12 x 12) ÷ (4 x 4)
= 81 in²
