Answer:

Perimeter = 15.5 cm

Step-by-step explanation:

Perimeter = sum of all sides

Perimeter = 5 + 1 + 1.5 + 2.5 + 2.5 + (5-1.5-2.5) + 2

perimeter = 5 + 1 + 1.5 + 2.5 + 2.5 + 1 + 2

perimeter = 15.5cm

The product of (a + b)(a − b) is a2 − b2. (1 point) Sometimes Always Never

jenyasd209 [6]

ANSWER

$\boxed{Always}$
EXPLANATION

The given product is

$( a - b)(a + b)$

This is always equal to

${a}^{2} - {b}^{2}$

The identity

$( a - b)(a + b) = {a}^{2} - {b}^{2}$

is called difference of two squares.

We can verify this by simply expanding the brackets using the distributive property to obtain,

$( a - b)(a + b) = a(a + b) - b(a + b)$

$( a - b)(a + b) = {a}^{2} + ab - ab- {b}^{2}$

This simplifies to

$( a - b)(a + b) = {a}^{2} - {b}^{2}$
