umm cant really explain
Answer:
Step-by-step explanation:
a
sum of angles of a quadrilateral=360°
4x+5x+20+5x-10+3x+10=360
17x=360-20
17x=340
x=340/17
x=20
b.
sum of angles= (n-2)×180
where n is the number of sides.
5x+4x+2+5x+6+2x-2+3x+5+x-10=(6-2)×180
20x+1=720
20x=719
x=35.95
7j + 17 = 87
Subtract 17 from both sides.
7j = 70
Divide both sides by 7.
j = 10
<h3>The value of the unknown number, or j, is equal to 10.</h3>
<span>The curves x = y^2 - 4y and x = 2y - y^2 are two parabolas with vertices (-4,2) and (1,1), respectively.
</span>
The solutions (0,0) and (-3,3) of system

give the common points of these parabolas.
The area is calculated in the image.

It is possible for two different inputs to give you the same output. For example, -2 and 2 produce the same result: 5.
it is not possible to derive two different outputs from the same input. This is because a)
is a function making it impossible to have two outputs and b) for each value, if you square it, you only get one value, then adding one, making it one certain value.
