Answer:

None of the pairs of expressions are equal

Step-by-step explanation:

• 2n ≠ 2 +n

2n is the same as 2 times of n (expressed as a multiplication sign), while 2 +n is the addition of 2 to n.

•n² ≠ 2n

n²= n ×n

2n= 2 ×n

• 2n² ≠ (2n)²

Note that in the latter, there is a bracket which means that the square applies to both 2 and n.

(2n)²

= (2)² × n²

= (2 ×2)(n²)

= 4n²

Thus, none of the pairs of expressions are equal.

Find the area of the triangle enclosed by these lines with the following vertices. y = x, x = 0, y = 5 (0,0), (0,5), (5,5)

Lina20 [59]

The are of the triangle will be 12.5 units.

On marking the given vertices (0,0), (0,5), (5,5) of the triangle we get, the base of the triangle = 5 units and height of the triangle = 5 units.

Now, we know area of triangle = $\frac{Base * Height}{2} \\ \\ = \frac{5 *5}{2} \\ \\ = \frac{25}{2} \\ \\ = 12.5 units.$
