You can find the area of the rectangle and the triangle separately and then add them together which would result in 330in. I personally do not think you should use the trapezoid formula even though they said it is a trapezoid (a trapezoid is usually not shaped like that) but if you want to it would result in 270in.
Answer:
x=-2
Step-by-step explanation:
Step 1: Subtract 8x from both sides.
5x+6−8x=8x+12−8x
−3x+6=12
Step 2: Subtract 6 from both sides.
−3x+6−6=12−6
−3x=6
Step 3: Divide both sides by -3.
−3x
−3
=
6
−3
x=−2
Answer:

Step-by-step explanation:
Hello
<u>Let's note the original speed of the car v</u>
it means that in 1 hour he is going v miles
so to go 200 miles it takes ( in hour)

If the speed of the car is v+5 than to go 200 miles it takes (in hour)

and this time is one hour less so we can write

We can multiply by v(v+5) both parts of the equation so


Only one is positive and this is is

So the original speed is 29.22144... mph
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
