Answer:

117 mi²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = \frac{1}{2} h (b₁ + b₂), substitute values

   = \frac{1}2} × 6 × (14 + 25)

   = 3 × 39

   = 117 mi²

Step 1: Lowest Common Denominator (10):

- 6/10 + (-40/10) =

Step 2: Solve the parentheses:

- 6/10 - 40/10 =

Step 3: Subtract the fractions:

-46/10

Step 4: Simplify (Dividing by 2):

-23/5

Step 5: Converting the fraction to mixed number:

-4 3/5

Eighty-five more than the square of a number is the same as the square of the quantity that is 17 less than the number. What is
mario62 [17]
We can turn this word problem into the following equation:
x^2 + 85 = (x - 17)^2
  x^2 + 85 = x^2 - 34x + 289
           -85                       -85
_______________________
      x^2 = x^2 - 34x + 204                    
     +34x         +34x
_______________________
 x^2 + 34x = x^2 + 204
-x^2             -x^2
____________________
       34x = 204
Divide 34 on both sides
      x = 6.
The number is 6.

Find the equation of the line, where P is a point on the graph of the line.<br><br> m=2/3 , P(3,5)
Liula [17]

Answer:

The answer is

y =  \frac{2}{3} x + 3

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To write an equation of a line given a point and slope we have

y - y1 = m( x - x1)

where (x1 , y1 ) is the point and m is the slope

Equation of the line using point P(3 , 5) and m = 2/3 is

y - 5 =  \frac{2}{3} (x - 3)

y - 5 =  \frac{2}{3} x - 2

y =  \frac{2}{3} x + 5 - 2

We have the final answer as

y =  \frac{2}{3} x + 3

Hope this helps you
