5 \text { builders =} 3 \dfrac{1}{2}  \text { hours }

-------------------------------------------------------
Find 1 worker :
-------------------------------------------------------
1 \text { builders =} 3 \dfrac{1}{2}  \times 5 \text { hours }

1 \text { builders =} \dfrac{35}{2} \text { hours }

-------------------------------------------------------
Find 2 workers :
-------------------------------------------------------
2 \text { builders =} \dfrac{35}{2} \div 2 \text { hours }

2 \text { builders =} \dfrac{35}{4} \text { hours }

2 \text { builders =} 8.75 \text { hours }

-------------------------------------------------------
Find cost of 1 worker :

The total number of seats in a movie theater is calculated by adding the area of the upper section given by 8x2 and the area of
e-lub [12.9K]
8x^2+6x^2+4x=138  combine like terms on left side

14x^2+4x=138 since the number of seats in the from row is just 4x, subtract 14x^2 from both sides

4x=138-14x^2  that would be the general solution, if you wanted the actual number you would have to solve for x and then multiply that value by 4 to know what "4x" is...

14x^2+4x-138=0

14x^2-42x+46x-138=0

14x(x-3)+46(x-3)=0

(14x+46)(x-3)=0

2(7x+23)(x-3)=0, since x>0

x=3 and thus

4x=12 seats

So there are 12 seats in the front row addition.

What is the point-slope form of the equation for the line with a slope of -2 that passes through (1,4)?
morpeh [17]

\bf (\stackrel{x_1}{1}~,~\stackrel{y_1}{4})~\hspace{10em} slope = m\implies -2 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-4=-2(x-1)

Answer ASAP<br><br> Find the area
slavikrds [6]

In this problem, you are asked to find the area of the trapezoid. The formula in finding the area of the trapezoid is:

A = [(a + b)/2] x h

Where a = base 1

             b = base 2

             h = height

Substituting the given measurements to the formula:

A = [(1.7 m + 6.7 m) / 2] x 5 m

A = (8.4 m / 2) x 5 m

A = 4.2 m x 5 m

A = 21 m^2

Therefore, the area of the trapezoid is 21 square meters.
