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.

Feliz [49]

Answer:

W \le 6

Step-by-step explanation:

Given

Area = 60ft^2\ (max)

Length = 10ft

Required

Represent the width as an inequality

First, we represent the area as an inequality.

Area = 60ft^2\ (max)

max as used above means less than or equal to.

So, we have:

Area \le 60

The area of a rectangle is:

Area = L * W

So, we have:

L * W \le 60

Substitute 10 for L

10 * W \le 60

Divide both sides by 10

\frac{10 * W}{10} \le \frac{60}{10}

W \le \frac{60}{10}

W \le 6
