Answer:
17.7% rounded to the nearest tenth
Step-by-step explanation:
Well to find the percent of space the trapezoid takes up we need to find both areas.
To find the area of a Rectangle we do l*w.
So the l is 30 and the w is 16 so,
30*15 = 480m^2
To find the area of a Trapezoid .
So b1 is 20 and b2 is 14,
14 + 20 = 34
34/2 = 17
17 * h
17 * (5) = 85m^2
So now we make a fraction of the areas of the trapezoid and rectangle,
Now we simplify,
85/5 = 17
480/5 = 96
So 17/96 is in its simplest form so now we do 17/96 which is 0.1770833333
So to the following into a percent we move the decimal places 2 places to the right which is about 17.7% rounded to the nearest tenth.

Answer:
No -5 is not the solution, But x =-3 is the solution.
Step-by-step explanation:
Given:
We need to find the solution for above equation we get;
Solution:
Now when we put the value of x =-5 we get
hence -5 is not the Solution for given equation.
On Solving the above equation we get;
Now Combining the like terms we get;
Now Using Subtraction property we get;
Hence The solution to equation is -3.
