Answer:
ED ≈ 2.6 units
Step-by-step explanation:
Using the Sine rule in Δ DEF
=
= ( cross- multiply )
ED sin115° = 6.95 sin20° ( divide both sides by sin115° )
ED = ≈ 2.6 ( to the nearest tenth )
Answer:
6x^2 + 4x
Step-by-step explanation:
g(x) + f(x)
= -8x^2 - 3x + 5 + 2x^2 + 7x - 5
= -8x^2 + 2x^2 - 3x + 7x + 5 - 5
= - 6x^2 + 4x
