Answer:

X=5 is the solution

Step-by-step explanation:

If you plug 5 in the solution it will be equal to 100.

(5+15) (5) = 100

(20) (5) = 100

An arithmetic sequence is represented in the following table. Enter the
pentagon [3]

Answer:

122

Step-by-step explanation:

An arithmetic sequence means a number is added each term.  There is a term for where a number is multiplied as well.  But in this case the first number is -103, the second number is -94 and the third number is -85.  Can you tell what number is added each time?

The number is 9.  -103+9=-94 and -94+9=-85 and so on.  Now we want a way to find the term way further down the line.

Think of it doing it all at once.  -103+9+9 gets us the third term right?  so that's 2*9.  -103+3*9 would get us the fourth.  Hopefully that makes sense, but let me know if it doesn't.  But for a few more examples, if we want the fifth term we would do -103+4*9 and getting the tenth would need -103+9*9.  So basically we take the number term we want (in this case we want the 26th) and then take -103+ n*9, where n is the term we want minus 1, or in this case 25.  so that's -103+25*9

Let me know if you need more of an explanation.

max2010maxim [7]

Answer:

Step-by-step explanation:

The easiest way is to use the distributive rule. 15¾ = 15+ ¾

15¾*8 = (15+¾)8 = 15*8 + ¾*8 = 120+6 = 126

The students in a furniture making class make a tabletop shaped like the figure shown.
Rama09 [41]

Answer:

The area of the given figure is equal to the area of a rectangle with sides 5 feets by 6 feets less the area of four square cut-outs of side 1 feet.

Area of the rectangle = 5 x 6 = 30 square feets.

Area of the four square cut-outs = 4(1 x 1) = 4 x 1 = 4 square feet

Area of the given figure = 30 - 4 = 26 square feet.

Area of a triangle = 1/2 x base x height

i.e. 1/2 bh = 26

bh = 26 x 2 = 52

possible values of base and height = (1 and 52), (2 and 26), (4 and 13)

Step-by-step explanation:

Hope this helped.

A brainliest is always appreciated.
