The answer is B. Y= (2/3)X - 3
Answer:
A = 222 units^2
Step-by-step explanation:
To find the area of this trapezoid, first draw an imaginary horizontal line parallel to AD and connecting C with AB (Call this point E). Below this line we have the triangle CEB with hypotenuse 13 units and vertical side (21 - 16) units, or 5 units. Then the width of the entire figure shown can be obtainied using the Pythagorean Theorem:
(5 units)^2 + CE^2 = (13 units)^2, or 25 + CE^2 = 169. Solving this for CE, we get |CE| = 12.
The area of this trapezoid is
A = (average vertical length)(width), which here is:
(21 + 16) units
A = --------------------- * (12 units), which simplifies to:
2
A = (37/2 units)(12 units) = A = 37*6 units = A = 222 units^2
Answer:
First image: Q
Second image: I think B
Step-by-step explanation:
We need to find the value of n in the first equation, so you would do:
- 17 = -3 - 2n
Add 3 to both sides to cancel the -3 in the side of the n variable
- 14 = -2n
Next divide to get rid of the -2 because it is multiplied by the -2
7 = n
54 = 17n - (-3)
Since you know that a negative times a negative transforms into a positive this is what it would look like:
54 = 17n + 3
Subtract 3
51 = 17n
Divide by 17 and n would be
n = 3
5687.3 to the nearest mile is 5,687 miles
Because the number directly to the right of ur 7 is a 3....and since it is below 5, ur whole number stays the same....if that number would have been a 5 or above, u would have rounded ur whole number up 1 making it 5688.
