1. you do the equation but x would be 15 (how much money you can spend)

2. 5(d+1) is multiplication. you have to multiply the outside number to the inside ones. So 5*d would be 5d and 5*1 is 5 so 5d+5

3. 3x+9=6x
-3. -3
6-3= 3
9/3=3

You basically plug in the x in the equation, for example if x = 4 and the equation is y = 2x + 5 you plug in 4 and the equation becomes y = 2(4) + 5. you then multiply and get y=8+5. from here u just add it and u get ur answer

Figure ABCD - Figure EFGH
Colt1911 [192]
<h3><u>Answer:</u></h3>
  • 30.5 units
<h3><u>Step-by-step explanation:</u></h3>

We know that:

  • <u>Trapezoid ABCD has one side that is 25 unit. </u>
  • <u>The other 3 sides (AB, BC, and CD) are 12 units. </u>
  • <u>EF = 6 units</u>
  • <u>EH = 12.5</u>
  • <u>Trapezoid ABCD is congruent to Trapezoid EFGH</u>

<em>If the 3 sides of the trapezoid ABCD are the same sides, then side EF, FG, GH must be of the same length because of congruence. The value of FG and GH must be the same length as EF. We can clearly see in the picture that EF is 6 units. Hence, EF is 6 units, FG is 6 units, and GH is 6 units. The work of the perimeter is shown below.</em>

<u>Work</u>

  • => 6(3) + 12.5
  • => 18 + 12.5
  • => <u>30.5 units</u>

Hence, the perimeter of EFGH is 30.5 units.

Which polynomial is factored completely
Ket [755]

Answer: The correct option is c.

Explanation:

Reason for correct option:

3x(9x^2+1)

This expression cannot be factored further because (9x^2+1) is the complete factor. Therefore the option c is correct.

Reason for incorrect option:

5x^2-17x+14=5x^2-10x-7x+14=5x(x-2)-7(x-2)=(x-2)(5x-7)

Since the given expression can be factored further therefore the option d is incorrect.

4(4x^4-1)=4((2x)^2-1)=4(2x^2-1)(2x^2+1)

Since the given expression can be factored further. Therefore the option a is incorrect.

2x(y^3-4y^2+5y)=2xy(y^2-4y+5)

Since the given expression can be factored further. Therefore the option b is incorrect.
