Answer:

  114 square meters

Step-by-step explanation:

The figure decomposes into two congruent trapezoids, each with bases 15 m and 4 m, and height 6 m. The area formula for a trapezoid is ...

  A = 1/2(b1 +b2)h

__

Each trapezoid will have an area of ...

  A = 1/2(15 +4)(6) = 57 . . . . square meters

The figure's area is twice that, so is ...

  figure area = 2 × 57 m² = 114 m²

What is the approximate distance between the points (-3, -4) and (-8, 1) on a coordinate grid
tatyana61 [14]
\bf ~~~~~~~~~~~~\textit{distance between 2 points}
\\\\
\begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
%  (a,b)
&&(~ -3 &,& -4~) 
%  (c,d)
&&(~ -8 &,& 1~)
\end{array}\\\\\\ %  distance value
d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}
\\\\\\
d=\sqrt{[-8-(-3)]^2+[1-(-4)]^2}\implies d=\sqrt{(-8+3)^2+(1+4)^2}
\\\\\\
d=\sqrt{25+25}\implies d=\sqrt{2\cdot 25}\implies d=\sqrt{2\cdot 5^2}\implies d=5\sqrt{2}

60+60 - hour heads up
80x-each hour travels 80miles
And both have a variable (x) that represent the number of hours
Equation:
60+60x=80x
Combine terms:
60=20x
Divide both sides by 20:
X=3
Soooo that means at 3:00pm two trains will be at the same distance from Chicago which is 240 miles
Hope this helps
