maksim [4K]

Answer:

A). PR = 16.13 ft

B). QR = 9.64 ft

Step-by-step explanation:

Part (A).

From the figure attached,

ΔPQR is a right triangle,

m(PQ) = 14 ft

m(QR) = 8 ft

By applying Pythagoras theorem,

Hypotenuse² = (Leg 1)² + (Leg 2)²

(PR)² = (PQ)² + (QR)²

(PR)² = (14)² + (8)²

PR = √260

     = 16.125

     ≈ 16.13 ft

Part (B).

If PR = 17 feet

and PQ = 14 feet

By applying Pythagoras theorem in ΔPQR,

PR² = PQ² + QR²

(17)² = (14)² + (QR)²

(QR)² = 289 - 196

QR = √93

     = 9.644

     ≈ 9.64 ft

Which are the prime factors of the polynomial 24x4 – 3x? Check all that apply.
Luba_88 [7]

The  prime factors of the polynomial 24x4 – 3x are 3x, 2x -1 and  (4x2 + 2x + 1)

<h3>Prime factorization</h3>

Given the polynomial function expressed as:

24x^4 – 3x

Factorize

y = 24x^4 – 3x

Factor out the GCF

y = 3x(8x^3 - 1)


Factor the expression in parenthesis

y = 3x((2x)^3 - 1^3)

y = 3x(2x-1)((2x)^2 + 1^2 +2x)

y = 3x(2x -1)(4x^2 +2x + 1)

Hence the  prime factors of the polynomial 24x4 – 3x are 3x, 2x -1 and  (4x2 + 2x + 1)
