In the diagram, CE = 12 and BE = 5. Based on the given information, AE =

lubasha [3.4K]

Answer:

12 units

Step-by-step explanation:

From the given figure, it can be seen that AB=BC, thus

From ΔBEC, using the Pythagoras theorem, we have

$(EC)^{2}=(BE)^{2}+(BC)^{2}$

$(12)^2=(5)^2+(BC)^2$

$144=25+(BC)^2$

$119=(BC)^2$

$BC=\sqrt{119} units$

Now, from ΔABE, using the Pythagoras theorem, we have

$(AE)^2=(BE)^2+(AB)^2$

$(AE)^2=25+119$

$(AE)^2=144$

$AE=12 units$

Thus, the measure of AE is 12 units.

Answer:

exactly two factors

Step-by step Explanation:

A prime number is an integer, or whole number, that has only two factors: 1 and itself. Put another way, a prime number can be divided evenly only by 1 and by itself. Prime numbers also must be greater than 1. For example, 3 is a prime number, because 3 cannot be divided evenly by any number except for 1 and 3.

Solve the system of linear equations by using the elimination method: 4x+ y = 36 8x- y = 60

katrin [286]

Answer:

(8,4)

Step-by-step explanation:

y and -y cancels out leaving you with "12x=96"

that simplifies to "x=8"

Then you substitute 8 into the "x" from either equation and y should equal 4
