Answer:

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

As we are given, quadrilateral ABCD is square.

Means its diagonals will intersect each other at their mid point.

So,  AE =EC

5x-10=2x+5

5x-2x= 5+10

3x = 15

x = 5

It means AE = 5x-10 = 5(5)-10 = 25-10=15

AE = BE

So,

\frac{y}{3} = 15

y = 45

hence answer is 45.   :   Answer

Hope it will help :)

Lina20 [59]

Answer:

The answer is x=1

Step-by-step explanation:

-4(3x+6)+6=-30

-12x-24+6=-30

-12x-18=-30

-12x-18+18=-30+18

-12x=-12

-12x/-12=-12/-12

x=1

Consider the following piecewise-defined function.
Fittoniya [83]
In order to solve this, we need to select the function that meets our constraints. Since x^2 - 5 occurs when x is less than 3, and the x-value we are given is -4, we use the first function.

f(-4) = (-4)^2 - 5
f(-4) = 16 - 5
f(-4) = 11
