Answer:
r = -39
Step-by-step explanation:
So we are trying to solve the equation for r.
-6(2r + 8) = -10(r - 3)
Divide both sides by -2. (This will make distributing much easier.)
3(2r + 8) = 5(r - 3)
Distribute the 3 on the left side and the 5 on the right side,
6r + 24 = 5r - 15
Subtract 24 from both sides.
6r = 5r - 39
Subtract 5r from both sides.
r = -39
So now we have solve the equation.

Answer:
56 cm^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the base and h is the height
A = 1/2 (14) (8)
A = 56 cm^2
Decagon = 10 sides or 10 anglesTotal angle is equal to 360°
360° ÷ 10 = 36°
I haven't seen the image of A, that is why, I started with angle A as 36°
∠A = 36°∠B = 36° + 36° = 72°∠C = 72° + 36° = 108∠D = 108° + 36° = 144°∠E = 144° + 36° = 180°∠F = 180° + 36° = 216°∠G = 216° + 36° = 252°∠H = 252° + 36° = 288°∠I = 288° + 36° = 324°∠J = 324° + 36° = 360°
