Answer:

54 yd²

Step-by-step explanation:

The surface area of the prism is the sum of the areas of its faces. Opposite faces have the same area, so we can write the formula as ...

SA = 2(LW +WH +LH) = 2(LW +H(L +W))

Filling in the numbers, we have ...

SA = 2(6·3 +1(6 +3)) = 2(18 +9) = 54 . . . . square yards

The area is 54 square yards.

Solve the linear equation.<br><br><br><br> 7x+10=13(12x−3)+14x

sladkih [1.3K]

7x + 10 = 13(12x - 3) + 14x
7x + 10 = 156x - 39 + 14x
10 + 39 = 156x - 7x + 14x
49 = 163x
x = 49/163

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

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