Answer:
17
Step-by-step explanation:
Using the law of cosines in ΔABC
b² = a² + c² - (2ac cosB) ← substitute in values
= 25² + 28² - (2 × 25 × 28 × cos36.9°)
= 625 + 784 - 1400 cos36.9°
= 1409 - 1400 cos36.9° ( Take the square root of both sides )
b = ≈ 17 ( nearest whole number )
you subtracted 2y from both sides to each side getting 2y = 10x +8

Good evening,
Look at the photo below for the Answer.
:)
4x^2 + 4x -2
Use FOIL to solve (x+2) (x+2)
4(x^2 + 4x +4) - 6
Forgot to add graph
The answer is A
A because it's simply adding by 4 on the right-hand side.
