5v^2 + 25 = 115
5v^2 = 115 - 25
5v^2 = 90
v^2 = 90/5
v^2 = 18...take the square root of both sides eliminating the ^2
v = (+-) sqrt 18
v = 4.24 or v = -4.24
Answer:
Yes
Step-by-step explanation:
f(x) = x³ − 9x² + 11x + 21
f(3) = (3)³ − 9(3)² + 11(3) + 21
f(3) = 27 − 81 + 33 + 21
f(3) = 0
<span>Total lot - house -other side
=(56 ft 9 in) - (34 ft 10 in) - (5 ft 5 in)
=(55 ft 21 in) - (34 ft 10 in) - (5 ft 5 in)
=16 ft 6 in
Convert to inches: </span>16 ft x 12 in/ft)+ 6 in= Total in inches<span>192 in + 6 in= Total in inches
198 in= Total in inches
Check: One side + house + other side = Lot width
(5 ft 5 in)+(34 ft 10 in)+(16 ft 6 in)=Lot width
56 ft 9 in=Lot width, which equals the given.</span>
Isosceles triangle I think
