Answer:
x=17
Step-by-step explanation:
x-9=8
add nine on both sides
x-9+9=8+9
the nines on the side with the x cancel each other
x=17
Answer: 9 and 15
Explanation: For this problem we will be using the formula of the perimeter of the parallelogram and use algebraic equation to solve it.
"The perimeter of a parallelogram is 48cm"
-So we already know the perimeter of this polygon
-We don't know the other sides
-We know both sides are on a ratio of 3/5
-We know the formula for perimeter of a parallelogram is P=2(a+b)
Let's use the formula to solve this. First lets substitute values we know.
1.) Write the formula.
P=2(a+b)
2.) Replace any known values.
48=2(a+b)
3.) This part is the trick part. Since the sides of the parallelogram are on a ratio of 3:5, it means that the first side is 3 times more of any unknown value, while the second side will be 5 times more of that same value. knowing this we can turn this into an Algebraic equation.
48=2(a+b)
48=2(3x+5x)
4.) Solve.
48=2(3x+5x)
48=2(8x)
48=16x
48/16=16x/16
3=x; or x=3
5.) Now that we know our "unknown value", we can though it back into the ration to figure out the sides lengths.
First side length = 3x = 3(3) = 9
Second side length = 5x = 5(3) = 15
6). Therefore, the first side has the length of 9 and the second side has the length of 15.
7.) Check.
P=2(a+b)
P=2(9+15)
p=2(24)
p=48
48=48
Answer:
The most precise name for a quadrilateral ABCD is a parallelogram
Step-by-step explanation:
we have
A(2,3) B(7,2) C(6,-1) D(1,0)
Plot the quadrilateral'
using a graphing tool
The quadrilateral ABCD in the attached figure
Verify the length of the sides
the formula to calculate the distance between two points is equal to

step 1
Find distance AB
A(2,3) B(7,2)
substitute



step 2
Find distance BC
B(7,2) C(6,-1)
substitute



step 3
Find distance CD
C(6,-1) D(1,0)
substitute



step 4
Find distance AD
A(2,3) D(1,0)
substitute



step 5
Compare the length sides
AB=CD
BC=AD
Opposite sides are congruent
<em>Verify the slope of the sides</em>
The formula to calculate the slope between two points is equal to

step 1
Find slope AB
A(2,3) B(7,2)
substitute



step 2
Find slope BC
B(7,2) C(6,-1)
substitute



step 3
Find slope CD
C(6,-1) D(1,0)
substitute



step 4
Find slope AD
A(2,3) D(1,0)
substitute



step 5
Compare the slopes


The slope of the opposite sides are equal, that means, opposite sides are parallel
The slopes of consecutive sides are not opposite reciprocal, that means, consecutive sides are not perpendicular
therefore
The most precise name for a quadrilateral ABCD is a parallelogram
