Select the perfect square trinomial for each polynomial. (there are 2 correct answers)

question 1 options:

x^2−10x−25

x^2−18x+81

x^2+2x+1

x^2+7x+49

x^2−18x+81

x^2+2x+1

Step-by-step explanation:

we know that

A trinomial is a perfect square trinomial if it can be factored into a binomial multiplied to itself

so

Verify each case

case a) x^2−10x−25

we know that

therefore

Is not a perfect square trinomial

case b) x^2−18x+81

we know that

therefore

Is a perfect square trinomial

case c) x^2+2x+1

we know that

therefore

Is a perfect square trinomial

case d) x^2+7x+49

we know that

therefore

Is not a perfect square trinomial

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
