AleksandrR [38]3 years ago

6 0

Add 11x to both sides
6<11x+61
minus 61 from both sides
-55<11x
divide both sides by 11
-5<x
x>-5
x can be any number bigger than -5
so
-4,-3,-2,-1,0,1,2,3,4,5,5.23424,2pi, etc

Gennadij [26K]

Answer:

options are 3 and 4

Step-by-step explanation:

The difference of squares is defined as In option 1,

It can be written as

It is the sum of squares, therefore the option 1 is incorrect.

In option 2,

The number 40 is not a complete square of any number, therefore option 2 is incorrect.

In option 3,

It can be rewritten as

It is the difference of squares, therefore option 3 is correct.

In option 4,

It can be rewritten as

It is the difference of squares, therefore option 4 is correct.

We defined the operation of concatenation for sets of strings on p. 10, AB = { XY | X ∈ A and y ∈ B}Are the regular sets closed

lakkis [162]

Answer and Explanation:

Solution: The operation of concatenation for a set of string on p. and the set is

AB = {XY | X ∈ A and y ∈ B}.

We need to satisfy all these following properties to find out the standard set is closed under concatenation.

1- Union of two standard sets also belongs to the classic collection. For example, A and B are regular. AUB also belongs to a regular group.

2- Compliment of two standards set A and B are A’ and B’ also belonging to the standard set.

3- Intersection of two standards set A and B is A∩B is also a regular set member.

4- The difference between two regular sets is also standard. For example, the difference between A and B is A-B is also a standard set.

The closure of the regular set is also standard, and the concatenation of traditional sets is regular.

The electric bill in May was $248.00. In June the bill was $265.00. What is the percent of increase rounded to the nearest hundr

natali 33 [55]

1) May: 248$ and june 265$. The difference is 17$ and then you divide the difference with the old price: 17/ 248 = 6,85%
2) Same method, the difference is 59$ so 27,44%'
3) The difference is 9,5$ so you answer is 63,3%
<span>4) The difference is 10$ divided by the original price: 10/24 = 41,66%</span>

Find the area of the unshaded reason for these two problems

Taya2010 [7]

9514 1404 393

Answer:

a) 96 m²

b) 26,000 ft²

Step-by-step explanation:

The area of the unshaded region is the difference between the overall area of the rectangle and the area of the shaded region. It can also be found directly using the dimensions of the unshaded region.

a) We have the height of the right triangle, but need to know its base. The Pythagorean theorem can help with that. Let the base of the triangle be represented by x. Then ...

x² +16² = 20²

x² = 400 -256 = 144

x = √144 = 12

The area of the unshaded triangle is given by the formula ...

A = (1/2)bh

A = (1/2)(12)(16) = 96 . . . . square meters

b) The shaded area at upper left is a square 100 ft on a side. Its area is ...

A = s² = (100 ft)² = 10,000 ft²

The shaded area at upper right is a triangle with base and height 120 ft and 150 ft. Its area is ...

A = (1/2)bh = (1/2)(120 ft)(150 ft) = 9,000 ft²

The area of the overall rectangle is ...

A = LW = (300 ft)(150 ft) = 45,000 ft²

So, the unshaded area is ...

unshaded area = overall area - left shaded area - right shaded area

unshaded area = 45,000 ft² -10,000 ft² -9,000 ft² = 26,000 ft²
