Kylie explained that (negative 4 x 9) squared will result in a difference of squares because (negative 4 x 9) squared = (negativ
JulijaS [17]

A perfect square trinomial is the result in algebraic form which is obtained by solving the squared binomial expression. Kylie did not understand that this is a perfect square trinomial and she did not determine the product correctly. Thus the option C is the correct option.

Given information-

The expression for the given problem is,

(-4x+9)^2

<h3>Perfect square trinomial</h3>

A perfect square trinomial is the result in algebraic form which is obtained by solving the squared binomial expression.

The perfect square trinomial can be given as,

ax^2+bx+c

The given expression can be solved as,

(-4x+9)^2=(-4x+9)\times(-4x+9)\\(-4x+9)^2=-4x(-4x+9)+9(-4x+9)\\(-4x+9)^2=16x^2-36x-36x+81\\(-4x+9)^2=16x^2-72x+81

Hence Kylie did not understand that this is a perfect square trinomial and she did not determine the product correctly. Thus the option C is the correct option.

Ashley says that 5/10×100 equals 500, thousands is she correct use a place value chart to explain your answer
adelina 88 [10]
Ashley is wrong. I have no clue what a placement chart is but I'll solve it anyway.

(5/10)x100 = (5x100)/10 = 500/10 = 50

Help me please please
Wittaler [7]

Answer:

It is right

Step-by-step explanation:

Because the hypotenuse must be greater than all the legs, we have that 17 is the hypotenuse. So, we want to determine if 8^2+15^2=17^2.

8^2=8*8=64\\15^2=15*15=225\\17^2=17*17=289\\225+64=289\\

This means the triangle is indeed right!
