Answer:

(A) (3x-5)(3x-5)

Step-by-step explanation:

Perfect-square trinomials have this form:

a^2x^2 \± 2ab + b^2

And can be expressed as a squared binomial:

(ax \± b)^2

Which is the same as: (ax+b)(ax+b) or  (ax-b)(ax-b)

You can observe that (3x-5)(3x-5) (Shown in the option A) matches with the form (ax-b)(ax-b), therefore, it will result in a perfect square trinomimal.

You can verify this by applyin Distributive property. Then:

(3x-5)(3x-5)=\\=3^2x^2+(3x)(-5)+(3x)(-5)+5^2\\=9x^2-15x-15x+25\\=9x^2-30x+25

The result is a perfect square trinomial.

It A because the two mirror each other so you can simplify them to (3x−5)^2.

A base ball diamond is square.The distance from home plate to first base is 90 feet.what is the distance from home plate to seco
Elena-2011 [213]

Because it is square, the distance from home to first base is the same as first base to second base.


Home to First is one side of a right triangle, first to second is the second side of the right triangle and then home to second base would be the hypotenuse of a right triangle.


Using the Pythagorean Theorem we can solve for the hypotenuse:

Let C = the hypotenuse:

90^2 + 90^2 = c^2

8100 + 8100 = c^2

16200 = c^2

c = √16200

c = 127.279 feet, round to 127 feet.

3/4(8x-4)=7x+2 This is a linear equation please help!
aleksandrvk [35]

Simplify the left hand side by multiplying the terms in the parenthesis by 3/4, i.e. divide them by 4 and multiply them by 3:

\dfrac{3}{4}(8x-4)=7x+2 \iff 3(2x-1)=7x+2 \iff 6x-3 = 7x+2

Subtract 6x from both sides:

-3=x+2

Subtract 2 to both sides:

x=-5
