HELP PLEASEEE I NEED HELP QUICK Which of the following are properties of a perfect square trinomial? Select all
that apply.
A. The first and third terms must be perfect squares.
B. Neither of the perfect
squares can have a minus sign.
C. If the perfect square terms are A2 and B2 then the other term
must be 2 AB or -2AB.
D. None of the above is a property of a perfect square trinomial.

C) If the perfect square terms are A^2 and B^2 and other terms must be 2 AB and -2AB

Step-by-step explanation:

As,

Step-by-step explanation:

The Perfect Squares  are the squares of the integers

Perfect square trinominal is:   a² ± 2ab + b²  {which is (a±b)²}

So:

The first and third terms must be perfect squares and neither of the perfect  squares can have a minus sign and If the perfect square terms are A2 and B2 then the other term  must be 2AB or -2AB

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
