Answer:
C
Step-by-step explanation:
(3x+2)(x-7)
All you need to do is FOIL.
3x^2-7x+2x-14
3x^2-5x-14
It would 100% be 5.
but my explanation is kind of by look, basically it is one more than the four and one less than the 6 :)
Answer:
Option A
Step-by-step explanation:
Suppose ∠I = 30° in ΔHIF,
∴ ∠F = 60°
Now consider the ΔGFH,
∠G = 90° and ∠F = 60°
∴ ∠GHF = 30°
Also in ΔGHI,
∠G = 90° and ∠I = 30°
∴∠GHI = 60°
∴ ΔGFH ≈ ΔGIH ≈ ΔHIF
