Answer:
A and E
Step-by-step explanation:
A) 7 hrs in IDU will cost you $305.00 while SC cost $385
B) 4hrs in and SC will charge you more than IDU by $20
C) SC charges you more than IDU by $50 so IDU is more cost effective
D)SC will charge you $140 more than IDU but not $200
E) 55 x 3 = 165 while 35 × 3 105 plus 60 is 165 therefore it is the same

(w + 5)(w^2 + 3w)
F (w)(w^2) = w^3 add the exponents
O (w)(3w) = 3w^2
I (5)(w^2) = 5w^2
L (5)(3w) = 15w
New expression: w^3 + 5w^2 + 3w^2 + 15w
Combine like terms.
Final answer: w^3 + 8w^2 + 15w
chur best answer is gonna be E H F< = h_<f"5
Answer:
BC = 2.24 cm
AC = 1.99 cm
Step-by-step explanation:
well to start we have to know the relationships between angles, legs and the hypotenuse.
a: adjacent
o: opposite
h: hypotenuse
sin θ = o/h
cos θ= a/h
tan θ = o/a
θ = 40°
h = 3cm
a = AC
o = BC
first let's calculate BC
sin θ = o/h
o = sin θ * h
o = sin 40 * 3
o = 0.7451 * 3
o = 2.24 cm
BC = 2.24 cm
having one leg and the hypotenuse we can calculate the other leg with pitagoras
h^2 = c1^2 + c2^2
3^2 = 2.24^2 + AC^2
9 = 5.02 + AC^2
AC^2 = 9 - 5.02
AC = √ 3.98
AC = 1.99
