Answer:
Area of triangle formula:
A = b*h/2
B is 18 and h is 13
B is base and h is height.
18 * 13 is 234.
We must divide by two because just multiplying the two numbers would result in an area of a square, divide by 2 for a triangle.
234/2 =
117 km²
First, see how far she can go with 1 tank of gas:
160/5=32
32 x 20 = 640
Hope this helps!!

x = 5
<u>explanation</u>
70 + 23x - 5 + 110 + 14x = 360
first you group the like terms
23x + 14x + 70 - 5 + 110 = 360
then combine the like terms
<u>23x + 14x</u> <u>70 - 5 + 110</u>
37x + 175 = 360
subtract 175 from both sides
175 - 175 = 0 360 - 175 = 185
to get
37x = 185
divide both sides by 37
37x/37 = 0 185/37= 5
which gives you
x = 5
