Step-by-step explanation:
It has one angle that is greater than 90 degress and the other two are acute angles so this classifies as an obtuse triangle.
Take short showers. Turn water off when brushing teeth. Clean dishes quicker. Fix leaks. Use less water when doing laundry.
First you need to find the second base (b2) by plugging all the values into the area of a trapezoid formula.
A= 1/2 (b1+b2)h
After plugging it in you will find that b2= 21.3.
The questions is asking perimeter so you add all the sides together...
14.4+18.5+14.7+21.3= 68.9 ft

Answer:
It's all about the brackets.
Step-by-step explanation:
If we do (-4)^2, the brackets make it -4 x -4 and the two negatives make a positive of 16.
If we do -4^2, that means that the 4 is squared before putting the minus sign there so you have 4x4 = 16 then put the minus to get -16.
