Answer: (3x-5)(3x-5)

Step-by-step explanation:

A perfect square trinomial is a polynomial that can be expressed in the form of the square of binomial.

Or that is a square root of a binomial.

(3x-5)(3x-5)= (3x-5)^2

where 3x - 5 is a bionomial,

⇒  (3x-5)(3x-5) is a perfect square trinomial,

(3x-5)(5-3x) = -(3x-5)(3x-5)=-(3x-5)^2

But, -(3x-5)^2 is not a perfect square root of a binomial,

⇒ (3x-5)(5-3x) is not a perfect square trinomial,

(3x-5)(3x+5) = (3x)^2-(5)^2=9x^2-25

But, 9x^2-25 is not a perfect square root of a binomial,

⇒ (3x-5)(3x+5) is not a perfect square trinomial,

(3x-5)(-3x-5)=-(3x-5)(3x+5) = -[(3x)^2-(5)^2]=-9x^2+25

But, -9x^2+25  is not a perfect square root of a binomial,

⇒ (3x-5)(-3x-5) is not a perfect square trinomial,

Let m be the side length of the fourth smallest possible square with integer value of its area, and let n be the sum of all prim
Natali [406]

Answer:

510

Step-by-step explanation:

It's assumed 0 is not an integer.

M is obviously 2. The area of a square is the square of its side length. If this area must be an integer, then it must be the fourth integer, which is 4. The side length, M=\sqrt{4} = 2

A prime number is a positive integer which can be divided exactly by only itself and 1. In fact, it has only those two factors. The last statement excludes 1 as a prime number. Hence, the prime numbers less than 10 are 2, 3, 5 and 7. Their sum is N=2+3+5+7=17.

To evaluate MN(N-M),

2\times17(17-2)=34\times15=510

Lines ℓ and m are intersected by transversal t. ℓ ∥ m. Lines l and m are horizontal with l above m and intersected by transveral
artcher [175]

Answer:

<5 = 105 degrees

Step-by-step explanation:

From the description given, since line l is parallel to m then <4 is alternate to <5 and two alternate angles are equal, if thst is the case

<4 = <5 (alternate angle)

Since <4 = 105 degrees, hence m<5 = 105 degrees
