Which of the following expressions are equivalent to (x+y)^2? there may be more than one correct answer

The equivalent expressions are:

Solution:

We have to find the equivalent expression for the given expression

Given expression is:

Let us first use the algebraic identity

Therefore,

From above we get,

2xy can be rewritten as xy + xy

Thus we get,

Group the terms we get,

Factor out "x" from first bracket and "y" from second bracket

Thus the equivalent expression is:

Therefore,

By commutative property we know that,

Therefore,

Thus the equivalent expressions are found

70,000 + 6,000 + 800 + 30

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
