Question

3x-1 and 5x+2 find the area

Answer 1

Given:

• 3x - 1

• 5x + 2

To find out:

Find the area ?

Solution:

Area = ( 3x - 1 ) × ( 5x + 2 )

= 3x ( 5x + 2 ) - 1 ( 5x + 2 )

= 15x² + 6x - 5x - 2

= 15x² + x - 2

Thus, the area is 15x² + x - 2 .

Answer 2

Answer:

$= 15 {x}^{2} + x - 2$

Step-by-step explanation:

$(3x - 1) \times (5x + 2) \\ 3x(5x + 2 ) - 1(5x + 2) \\ 15 {x}^{2} + 6x - 5x - 2 \\ = 15 {x}^{2} + x - 2$

hope this helps
