Answer:

\huge\boxed{\sf x^2 = 16}

Step-by-step explanation:

\sf 3(x+5) +2 = 29\\\\Resolving \ Parenthesis\\\\ 3x + 15 + 2 = 29\\\\3x + 17 = 29\\\\Subtract \ 17 \ to \ both \ sides\\\\3x = 29-17\\\\3x = 12\\\\Divide \ 3 \ to \ both \ sides\\\\x = 12 / 3\\\\x = 4\\\\Take \ square \ on \ both \ sides\\\\x^2 = (4)^2\\\\x^2 = 16\\\\\rule[225]{225}{2}

Hope this helped!

Step-by-step explanation:

\huge{\underline{\underbrace{\mathcal\color{gold}{Answer}}}}

\tt{3(x-5)+2=29  } ⠀

\tt{3x-15=29-2  } ⠀

\tt{ 3x=27-15 } ⠀

\tt{ 3x=12 } ⠀

\tt{ x=\dfrac{12}{3} } ⠀

\tt{x=4  } ⠀

So,

According to the question,

\tt{  x^2=x×x=4×4=16} ⠀

George and Chin work as landscapers. George charges $90 for a 6-hour job. Chin charges $84 for the same job.The table shows thei
gulaghasi [49]
The equation must equal 84, so you can eliminate B and D.

Chin charges a rate for 2 hours, then charges a reduced rate for 4 hours. There are no discounts present in his rate, so you can eliminate A.

The equation for Chin's charges can be found by the equation C. 2x + 4y = 84.

Solve the equation below using a graphing
UNO [17]

Answer:

<em>x = 0.05</em>

<em>x = 1.57</em>

Step-by-step explanation:

The given equation is:

e^x-\ln 2x = 3.7

Moving all terms to the left side:

e^x-\ln 2x - 3.7=0

Now we define a function:

y=f(x)=e^x-\ln 2x - 3.7

The solutions of the equation are the values of x such that y=0.

Since the function cannot be solved by algebraic methods, we use a graphing tool.

Those points where the graph crosses the x-axis are solutions of the equation.

Please refer to the graph in the figure below.

We can clearly identify there are two solutions at

x = 0.05

x = 1.57

Y=2 Enter the solution (x, y) to the system of equations shown 7y+3x=5
AnnyKZ [126]

Answer:

(x, y) = (-3, 2)

Step-by-step explanation:

Put the given value of y into the equation and solve for x.

... 7·2 +3x = 5

... 3x = -9 . . . . . . subtract 14

... x = -3 . . . . . . . divide by the x-coefficient

The solution (x, y) is (-3, 2).
