Answer 1

Answer:

Hope it helps.

Step-by-step explanation:

x³ - 2x² - 9 + (5x³ + 2x + 9 )

⇒ x³ - 2x² - 9 + 5x³ + 2x + 9

⇒ x³ + 5x³ + 2x² + 2x [ We have written the like terms together]

⇒  6x³ + 2x² + 2x

Answer 2

Answer:

The area of the triangle will be 270 cm²

Step-by-step explanation:

Here the measure of base and the height of a triangle is given to be 30 cm and 18 cm respectively

We have to find the area of the triangle

The area of a triangle is given by half the product of its base and height

Area of triangle = (1/2) × base × height

= (1/2) × 30 × 18

= 15 × 18

= 270 cm²
