Answer:
Area ABCDE = 82 cm²
Step-by-step explanation:
ABCDE = ΔEAD + ΔDAC + ΔCAB
ABCDE = (12×5)/2 + (12×6)/2 + (8×4)/2 = 30+36+16 = 82
By the Intersecting Secants Theorem we have
2x(2x+7)=x(x+23)
4x^2+14x=x^2+23x
3x^2=9x
3x=9
x=3
Since DY is length 2x,
the length of DY is 6.
Answer:
x₁ = 15 xₙ = x₁ * 7 * n n>1
Step-by-step explanation:
150
2100 = 150 x 7 x 2
3150 = 150 x 7 x 3
4200 = 150 x 7 x 4
x₁ = 150
xₙ = x₁ * 7 * n n>1
