What is Expression?

A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. Let's examine the writing of expressions. The other number is x, and a number is 6 greater than half of it. In a mathematical expression, this proposition is denoted by the expression x/2 + 6.

As an illustration, the phrase x + y is one where x and y are terms with an addition operator in between.

Given statement:

a number t cubed

Here the number be t.

So, the number t is cubed which can be written as

= t³

Hence, the expression is t³.

can someone tell me the answer to this please..?

Answers

Answer:

x=8

this is because you do 57+89=146

and then you do 180-146 because a triangle adds up to 180.

this gives you 34

so the value of 5x-6=34

add the 6 onto 34 which gets rid of the -6 ans fives you the answer of 40

After that yoy divide 40 by 5 which gives you the value of x which is 8

Find the measure of the largest angle in the triangle shown . PLS HELP

Answers

Answer:

72°

Step-by-step explanation:

So the three angles of a triangle always add up to 180°. This means that

[tex]15x + 21x + 24x = 180[/tex]

This becomes:

[tex]60x = 180[/tex]

And solves as:

[tex]x = 3[/tex]

The largest angle has to be the one marked with 24x because it has the largest coefficient and x is a constant.

[tex]24x = 24(3) = 72[/tex]

The measure of the largest angle in the triangle is 72°.

72 degrees is the biggest angle in the given triangle.

What are the properties of the triangle?

The properties of the triangle are: The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.

Given that the three angles of the triangle are 24x, 21x, and 15x

Since the sum of all the angles of the triangle is always 180 degrees

Thus,

24x +21x + 15x = 180

60x = 180

x = 3

Thus, the biggest angle would be 24x

biggest angle of triangle = 24 * 3 = 72

Therefore, the biggest angle of the given triangle is 72 degrees

Step-by-step explanation:gfdgdfg

The area of the garden is increased by 20 % . If the width remains the same, then the new length of the garden is 2.4 yards.

What is Area of Rectangle?

The area of Rectangle is length times of width.

Given that A decorative fence surrounds a rectangular flower garden that is 2 yards long and 3 yards wide

Area = Length × Width

Area=6 yards.

The area of the garden is increased by 20 % .

20/100=0.2

the area would equal 6 (l x w) and 6 increased by 20% equals 7.2.

As the width remains same

so we use 7.2/3 to find the new length

7.2/3=2.4 yards.

Hence, 2.4 yards is the new length of the garden.

For homework plss help

Answers

Answer:

B, C, D and E are correct options

Step-by-step explanation:

Here, we want to get the correct options;

a. We simply divide the next term by the previous term so that we get the common ratio

That would be 16/-8 = -32/16 = -2

As we can see, the common ratio is -2 which means that the option cannot be correct

b. The 5th term is mathematically;

ar^4 = -8 * (-2)^4 = -8 * 16 = -128

This is correct

c. The 7th term is

ar^6 = -8 * (-2)^6 = -512

5th term is ar^4 = -8 * (-2)^4 = -128

So -512/-128 = 4

As we can see, this option is correct

d. 8th term is 1024

8th term is ar^7

= -8 * (-2)^7 = 1024 which is correct

e. 10th term is ar^9 = -8 * (-2)^9 = 4096

9th term is ar^8 = -8 * (-2)^8 = -2048

This is correct
