Answer:

13 < x < 21.

Step-by-step explanation:

First the third side (x) must be less than 4 + 17 , that is  < 21.

Also 17 cannot  be greater than  4 + x:

17 < 4 + x

x > 13.

Step-by-step explanation:

Solve by factoring

9x^2 + 24x + 16       Find two numbers that  their product is 144 and their sum is 24.   The numbers  12 and 12 works out because 12 times 12 is 144 and 12 plus 12 is 24.

Rewrite the expression in a new way like,

9x^2 + 12x + 12x  + 16         Now factor by grouping them into two groups

(9x^2 + 12x) ( 12x + 16)     Now factor each group by using the greatest GCF

3x ( 3x + 4) 4( 3x + 4)     Factor out 3x +4  

(3x + 4) ( 3x + 4)

Answer:

6/28 + 3/4 = 3/14 + 3/4 = 2/28

Step-by-step explanation:

Answer:

27/28

Step-by-step explanation:

To get this answer, you need a common denominator. In this case, a common denominator would be 28. So, you leave 6/28 the same. Now, you need 2 convert 3/4 to 28ths. So, 4 (denominator) times what is 28? Well, 4 times 7 is 28. Whatever you do to the top, you do the bottom. So 3 times 7 is 21. Now, you have an equivalent fraction that is 21/28. Now you can add.

So, 6/28 + 21/28 is equal to 27/28.

Answer:

A

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

x + 2x + 3x = 180

6x = 180 ( divide both sides by 6 )

x = 30 → A

Answer:

A) 30

Step-by-step explanation:

The sum of all of the angles in a triangle have to equal 180 degrees.

Plug in 30 for x

3(30) = 90

2(30) = 60

(30)= 30

90+60+30= 180

Therefore x=30 degrees

Answer:

9[tex]\sqrt{3}[/tex]

Step-by-step explanation:

divide the triangle in 2

this makes the height = 3

since it is a 30 60 90 triangle, 1/2 of the base would be 3[tex]\sqrt{3}[/tex]

multiply this by 2 to get 6[tex]\sqrt{3}[/tex] for the base

you can then find the area by multiplying (1/2)*(6[tex]\sqrt{3}[/tex])*3 = 9[tex]\sqrt{3}[/tex]

The solution to the inequality 3600 +1.02x < 2000 +1.04x is x > 80000.

An inequality is an expression that shows the non equal comparison of two or more variables and numbers.

Given the inequality:

3600 +1.02x < 2000 +1.04x

Collecting like terms:

1.02x - 1.04x < 2000 - 3600

-0.02x < -1600

x > 80000

The solution to the inequality 3600 +1.02x < 2000 +1.04x is x > 80000.

Answer:

-140.4

Explanation:

-68.25 -72.15 = -140.4

Answer:

y=65 and x=25

Step-by-step explanation:

since 65 and x create a 90 degree angle, you subtract 90-65 to get the x (25.) and then since x and y ALSO make a 90 degree angle you subtract 90-25 to get y (65.)

I can try to help. whats your issue with algebra?

Answer:

Step-by-step explanation:

What exactly is your difficulty can you be more specific perhaps?

If I give give you a formulae e.g. N= P¥s/ yR^2 and I don't say what each letter or symbol represents then its meaningless but if I state S = d/t and say that S = speed of an object and that equates to d (distance) divided by t (time) then hopefully you will know and be able to relate to the overall formulae

In my earlier study years I had to learn complex electrical and mechanical formulae e.g. Xl = 2pi f L ( Electrical Inductive Reactance) and its all about finding a strategy that works for you.

You have to get familiar with formulae and thats by practice, the more you use them the more you tend to remember them

Step-by-step explanation:

Answer:

140

Step-by-step explanation:

180 - 40 = 140

reverse operations

140 + 40 = 180

Applying algebra and assuming the unknown value is x, we can determine that 40 plus 140 equals 180.

To solve the equation "40 plus what equals 180," we can use algebraic notation. Let's denote the unknown value as "x." The equation can be represented as:

40 + x = 180

To find the value of x, we can isolate it on one side of the equation by performing the same operation on both sides. In this case, we subtract 40 from both sides:

40 + x - 40 = 180 - 40

x = 140

Therefore, 40 plus 140 equals 180.

12x + 6 - 8x + 7

= 12x - 8x + 6 + 7

= 4x + 13

Now multiplication with first part

4x + 1

(4x + 13) * (4x +1)

=4x * (4x +1) + 13 * (4x +1)

=16x^2 + 4x + 52x + 13

=16x^2 + 56x + 13

Now multiplication with second part

20x + 1

(4x + 13) * (20x + 1)

=4x * (20x + 1) + 13 * (20x + 1)

=80x^2 + 4x +260x + 13

=80^2 + 264x + 13

Now multiplication with third part

4x + 13

(4x + 13) * (4x + 13)
