Answer:
Area of the triangle = 0
Step-by-step explanation:
We are given the vertices of a triangle as: (- 8,4 ), (- 6,6), (- 3,9)
The formula to find the Area of the triangle =
1/2[ x₁(y₂ - y₃) + x₂(y₃ - y₁) + x₃(y₁ - y₂)]
Where :
(x₁, y₁) = (- 8,4 )
(x₂, y₂) = (- 6,6)
(x₃, y₃) = (- 3,9)
Area of the triangle = 1/2[-8(6 - 9) + -6(9 - 4) + -3(4 - 6)]
= 1/2[ (-8 × -3) +( -6 × 5) +( -3× -2)]
= 1/2[ 24 - 30 + 6)
= 1/2[ 24 + 6 - 30]
= 1/2 [30 - 30]
=1/2[ 0 ]
= 0
Therefore, the area of triangle whose vertices are (- 8,4 ), (- 6,6) and (- 3,9) is ZERO( = 0 )
The answer is -47-10w=-9w-40-3w bc the equation above equals 7/2 and this equation does too first combine like terms -47-10w=(-9w+3w)+40 which gives you -10w-47=-12w-40 then Add 12w to both sides which gives you 2w-47=-40 and then Add 47 to both sides and gives you 2w=7 and then divide 2 in both sides and gives you 7/2
Answer:
16 half hours.
Step-by-step explanation:
There are 2 half hours in each hour, multiply 8 by 2 get 16.
