Answer:

The correct answer is first option

(7x + 4)(7x − 4)

Step-by-step explanation:

<u>Points to remember</u>

<u>Identities</u>

(a + b)(a - b) = a² - b²

It is given an expression,

49x² - 16

<u>To factorize  the expression 49x² - 16</u>

We know that 7² = 49 and 4² = 16

Therefore we can write the given expression as,

49x² - 16 = (7x)² - 4²

It is in the form of the above identity,

(7x)² - 4² = (7x + 4)(7x - 4)

The correct answer is first option

Hi! Can someone help me please.
Sati [7]

Answer:

27 inches

Step-by-step explanation:

We are using the Pythagorean theorem

a^2 +b^2 = c^2  where c is the hypotenuse

We are given the diagonal, which is the hypotenuse and a leg

36^2 + b^2 = 45^2

Subtract 36^2 from each side

36^2 + b^2 - 36^2 = 45^2 - 36^2

b^2 = 45^2 - 36^2

     b^2 =2025-1296

          b^2 =729

Take the square root of each side

sqrt(b^2) = sqrt(729)

b =27
