Here: (Aₓ, Ay) = (-3,-4), (Bₓ, By) = (-7,0), (Cₓ, Cy) = (-3, 4)
Now, Formula of area of triangle is:
area = [Aₓ(By - Cy) + Bₓ(Cy - Ay) + Cₓ(Ay - By)] / 2
Substitute the values in to the expression,
area = [-3(0-4) - 7(-4-(-4)) - 3(-4-0)] / 2
area = [-3(-4) -7(0) -3(-4)] / 2
area = [12-0+12] / 2
area = 24 / 2
area = 12
Final answer would be 12 units.
Hope this helps!
Factor by grouping.
(7x+2)(x-2) I think not sure
Supplementary angles measure 180°. Make an equation:

Subtract 28 to leave the variable in the parentheses alone:

Add the 2 x's together:

Your new equation is:

Divide both sides by 2 to leave the variable alone

The supplement measures 76°
Answer:
50 cm² and 56 cm²
Step-by-step explanation:
The area (A) is calculated as
A =
× d₁ × d₂ ( d₁ and d₂ are the length of the diagonals )
(2)
A =
× (8 + 2) × (5 + 5)
= 0.5 × 10 × 10
= 5 × 10
= 50 cm²
(3)
A =
× (12 + 2) × (4 + 4)
= 0.5 × 14 × 8
= 7 × 8
= 56 cm²
Answer:
the answer is -5/6 hope this helps
