Answer:
A ≈ 2.95 ft²
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = 
product of 2 sides × sine of angle between them , then
A = 0.5 × 2.7 × 3.4 × sin40° ≈ 2.95 ft² ( to the nearest hundredth )
Answer:
The system has no solution.
Step-by-step explanation:
Write the system as
y - 4x =3
2y - 8x = 3
The 2nd equation can be written as
2(y - 4x)
and the system would be
y - 4x =3
2(y - 4x) = 3
Now, call y -4x = z. Then we would have the system
z = 3
2z = 3
But if z =3 then 2z = 6 and we have a contradiction.
We conclude that the system has no solution.
