Let us first try and solve this equation to see how many solutions are for this equation.

We need to have x on one side of the equation and everything on the opposite side of x.

<span>1/2(4x - 9) = 2x + 8 ; Start
2x - 4.5 = 2x + 8     ; Distribute the 1/2 across 4x and -9
2x = 2x + 12.5        ; Add 4.5 to each side of the equation
0 = 12.5                  ; Subtract 2x from each side of the equation

As we can clearly see, this equation has 0 answers.</span>

Simplify the following expression by combining like terms.
Aleks04 [339]

Answer:

8x^2+3x

Step-by-step explanation:

What I read is 2x+8x^2-4x+5x

combining like terms means putting the terms that have the same variable part together

8x^2 is the only one that doesn't have any terms like it as far as the variable part

so 8x^2+2x-4x+5x

We just need to figure out 2-4+5 which is -2+5=3

So the answer is 8x^2+3x

Write the first five terms of the sequence defined by the explicit formula an=-4n(n-1)
vladimir2022 [97]

The explicit formula of the sequence is given by a_n = -4n(n-1).

We have to find the first five terms of the sequence.

The first term:

\begin{gathered} a_1=-4\times(1)(1-1) \\ =-4(0) \\ =0 \end{gathered}

The second term:

\begin{gathered} a_2=-4(2)(2-1) \\ =-8(1) \\ =-8 \end{gathered}

The third sum:

\begin{gathered} a_3=-4(3)(3-1) \\ =-12(2) \\ =-24 \end{gathered}

The fourth term:

\begin{gathered} a_4=-4(4)(4-1) \\ =-16(3) \\ =-48 \end{gathered}

The fifth term:

\begin{gathered} a_5=-4(5)(5-1) \\ =-20(4) \\ =-80 \end{gathered}

Thus, option D is correct.

Please help with this area question. I have gotten my answer but I am not too sure about it, and want to make sure my reasoning
Pie

Answer:

D

Step-by-step explanation:

Area of triangle= ½ ×base ×height

Since the length of the base and the height of the triangle is equivalent to the length of a side of the square, s,

area of triangle

= ½ ×s ×s

= ½s²

Given that the area of the triangle is 12.5 units²,

½s²= 12.5

Multiply both sides by 2:

s²= 12.5(2)

s²= 25

Square root both sides:

s =  \sqrt{25}

s= 5 units

(reject negative value since s > 0)
