Answer:

A=675cm²

Step-by-step explanation:

Area of triangle=1/2(base × height)

A=1/2(b × h)

A=1/2(6x × 9x)

where x=5

A=1/2(6×5×9×5)

A=1/2(30×45)

A=1/2(1350)

divide 1350 by 2

A=675cm²

m_a_m_a [10]

Answer:

 45x^3 + 123x^2 + 104x + 28

=(45x^3 + 60x^2 + 20x) + (63x^2 + 84x + 28)

=(5x + 7)(3x + 2)^2

=> Option D is correct

Hope this helps!
