In parallelogram ABCD , diagonals AC and BD intersect at point E, BE=x^2−40 , and DE=6x .What is BD ? The answer was 120

Leviafan [203]

Answer:

120

Step-by-step explanation:

Given that ABCD is a parallelogram.

We know that in a parallelogram diagonals bisect each other.

Since AC and BD intersect at E, we get E is the mid point of both AC and BD.

Or BE = ED

Substitute the given values for BE and ED

$x^2-40 = 6x\\x^2-6x-40=0\\(x-10((x+4) = =0$

i.e. x =10 or x =-4

But x cannot be negative . So x can take only value 10

BE = DE =6x = 6(10) = 60

Diagonal BD = BE+DE = 60+60 = 120

Answer is 120

marta [7]

Answer:

The answer is 16%

Step-by-step explanation:

use the percent error formula.

$\frac{|E-T|}{|T|} *100$

in this problem,

e= 75

t=90

substitute and solve.

$\frac{|75-90|}{|90|} *100\\\frac{|-15|}{|90|}*100\\\\ .16667*100\\$

16%

we are dealing with percents so rounding to nearest whole number will suffice.

hope this helps!

If all the edges of prism A are multiplied by 5 to create prism B. The volume of prism B will be __________ times the volume of

Ne4ueva [31]

Answer:

125

Step-by-step explanation:

Say prism A is a cube, and all the sides are x, then the volume of prism A is $x^3$ .

If you multiply each side by 5 (prism B), then each side is 5x, so the volume of prism B is $125x^3$ , which is 125 times more than $x^3$ .
