Answer with Step-by-step explanation:

The area of trapezoid is given by:

A=\dfrac{1}{2}\times (sum\ of\ bases)\times height

Here we are given Area=390 km²

Sum of bases=(23+29) km

                      = 52 km

We have to find the height of trapezoid

Putting all the given values in the formula of area of trapezoid

390=\dfrac{1}{2}\times 52\times height

390=26×height

height=15

Hence,height of trapezoid is:

15 km

Hello!

To find the area of a trapezoid you use the equation

A =  \frac{a+b}{2} h

Put in the values you know

390 =  \frac{23+29}{2} h

Add

390 = \frac{52}{2} h

Divide

390 = 26 * h

Divide both sides by 26

15 = h

The answer is 15km

Hope this helps!

Complete the table using the equation y = 9x + 8.
Volgvan

Answer:

Y  =  (  -1) | 8 | 17 | 26 | 35|

Step-by-step explanation:

y = 9x + 8  \\ \\  \\ x = ( - 1) \\ y = 9( - 1) + 8 \\ y =  - 9 + 8 =  - 1 \\  \\ x = 0 \\ y = 9(0) + 8 \\ y = 0 + 8 = 8 \\  \\ x = 1 \\ y = 9(1) + 8 \\ y = 9 + 8 = 17 \\  \\ x = 2 \\ y = 9(2) + 8 \\ y = 18 + 8 = 26 \\  \\ x = 3 \\ y = 9(3) + 8 \\ y = 27 + 8 = 35 \\  \\  \\  Y  =  (  - 1) | 8 | 17 | 26 | 35|
