In parallelogram ABCD , diagonals AC¯¯¯¯¯ and BD¯¯¯¯¯ intersect at point E, AE=2x2−3x , and CE=x2+4 .

spin [16.1K]

If the diagonals of the parallelogram intersect with each other, this means that the diagonals bisect each other. Thus,

AE = CE

Substituting the equations,

2x² - 3x = x² + 4

The values of x from the equation are equal to 4 and -1.

AE = 2(4)² - 3(4) = 20

Hence, AC is equal to 40.

How to add a + b using 45a +90b

yulyashka [42]

Answer:

45(a + 2b)

Step-by-step explanation:

45a

step1 in order to factor an integer, we need to repeatedly divide it by the ascending sequence of primes (2, 3, 5...) The number of times that each prime divides the original integer becomes its exponent in the final result

Prime number 3 to the power of 2 equals 9 .

Prime number 5 to the power of 1 equals 5 .

$3x^{2} *5$

90b

do the same as above

Prime number 2 to the power of 1 equals 2 .

Prime number 3 to the power of 2 equals 9 .

Prime number 5 to the power of 1 equals 5 .

$3x^{2} *5*2$

What i the solution to this equation<br> 6 (x - 5) = 4x + 20

cricket20 [7]

6 (x - 5) = 4x + 20

6x - 30 = 4x + 20

6x - 4x = 20 + 30

2x = 50

$x = \frac{50}{2}$

x = 25

Legend has it that a bull sasquatch in rut will howl approximately 9 times per hour when it is 40°f outside and only 5 times per

ahrayia [7]

The answer is 13.

To solve this question, you need to determine the slope of the function. if howl is y and the temperature is x of the graph, the slope would be:

9-5/(40-70)= 4/-30= -2/15

Using one of the point and the slope, you can find the number of howl

-2/15= 9-y/40-(-20)

9-y= -2/15 * 60

9-y= -4

y= 9+4= 13
