Answer:
Step-by-step explanation:
1). x² - 10x + a²
By using the formula of (a - b)² = a² - 2ab + b²
x² - 2(5)x + a²
Therefore, for a perfect square of the expression a should be equal to 5.
Therefore, (x² - 10x + 25) will be the answer.
2). x² + 2ax + 36
= x² + 2(a)x + 6²
For a perfect square of the given expression value of a should be 6.
x² + 2(a)x + 6² = x² + 2(6)x + 6²
= (x + 6)²
Therefore, x² + 12x + 36 will be the answer.
3). 

To make this expression a perfect square,
a² = 
= 
Therefore, the missing number will be
.
<h3>
Answer:</h3>
32
<h3>
Step-by-step explanation:</h3>
Divide 192 by 6, to find the amount of baseball cards Nick has.
192 ÷ 6 = <u>32</u>
<h3><u>
Check:</u></h3>
32 · 6 = 192
192 ÷ 6 = 32
Nick has 32 baseball cards, which is 6 times less than Juan's amount.
Answer:
x=4
Step-by-step explanation:
Consider the coordinate pair (4,y)
We observe that,
y can take any real values to lie on the graph of the equation.
As y really isn't a constant, we exclude it and take the equation as x=4
You first have to find out how many bags you have in total. So you multiply the number of boxes with the number of bags. After that you get the number of bags and multiply it with the number if melons in each bag.
30×2=60bags
60×3=180melons
Hello There!
Ethan would pay $31.99 or rounded up two 32 which ever is your answer choice
Thus being why.
if you times 39.99 x .20 you get 7.998
39.99 - 7.998 is 31.99
Hope This Helps!
