Can any one help me with this please

x = 19

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = h (b₁ + b₂ )

h is the perpendicular height and b₁ , b₂ the parallel bases

Here A = 180.5 , h = x , b₁ = 13 and b₂ = 6 , then

x (13 + 6) = 180.5 ( multiply both sides by 2 to clear the fraction )

x × 19 = 361 ( divide both sides by 19 )

x = 19

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
