Answer:
BD = 20 units
Step-by-step explanation:
Given that,
Parallelogram ABCD has diagonal segments AC and BD that intersect at E.
BE = (x+8) and ED = 5x
We need to find the length of BD.
BD = BE + ED ...(1)
We know that the diagonals of a parallelogram bisects each other. It means,
BE = ED
x+8 = 5x
8 = 5x - x
8 = 4x
x = 2
BE = (x+8)
= (2+8)
= 10
ED = 5x
= 5(2)
= 10
Put the values in equation (1).
BD = 10 + 10
= 20 units
Hence, the length of BD is 20 units.
Answer:False, true, true, false
Step-by-step explanation:
The first one is false because 2 & 5 equal 180 together. B is true because they equal the same thing. C is true because they equal 180 together. And D is false because those don’t equal 180.
The expression which shows the total area of the picture and frame is 
+320.
Given that the width of the frame is x ,length horizontally be 20 inches and vertically be 16 inches.
We are required to find the expression which shows the total area of the picture and frame.
Expression is basically a combination of numbers, symbols, coefficients, determinants, indeterminants,etc. and are mostly not found in equal to form.
Since we are given that the width of the frame be x, So,the are of only frame will be :
Area of frame=20*x*2+16*x*2+x*x
=40x+32x+
=+72x
Area of picture=20*16=320 
The expression which shows the total area of the picture and frame is +320.
Hence the expression which shows the total area of the picture and frame is +320.

×=3
first all you have to figure out is what x equal so to figure out and solve what x is all you have to do is try to think 42 times what would give you 126 or you could just divide 126÷42 when you do all of that your answer will be 3
exhibit population for ten integers is 15,19,19,20,20,20,21,22,22,22 mean is 20 variance is 4
Step-by-step explanation:
- Mean is helps in finding the mid point of the data.
- Variance is the variability of data it was here.
- In order to get the data straight the combination of 4 was required.
- 4 is variance one data set was 19 other had to be 22.
- As mean is 20 three means had to be 20.
- from mean 20 4 is greater then 20 and 3 is less then 20.
- 15 being the lowest it compensated the variance to 4.
- Mathematically there are many ways to do this using function.
- This is to be found out at a traditional method.
- Reducing or increase the number as it was integers.
