Answer:
n = -11
Step-by-step explanation:
Assuming you need to solve for n:
12 - n = 23 (Given)
-n = 11 (Subtract 12 on both sides)
n = -11 (Divide -1 on both sides)
Answer:
143x/12
Step-by-step explanation:
AREA =(X²-144X)m²
LENGTH =(X+12)m
THEREFORE, WIDTH =AREA/LENGTH
=(X²-144X/X+12)
OR,(X×X-144X/X+12)m
=(143X/12)m

Answer:
D) 25π/2 in²
Step-by-step explanation:
The area of a sector of central angle θ and radius r is ...
... A = (1/2)r²θ
Your sector has central angle π/4 and radius 10 in, so has area ...
... A = (1/2)(10 in)²(π/4)
... A = 25π/2 in² . . . . matches selection D
