we are given
side of square =s=6y+4
now, we know that
perimeter of square = 4*side
so,

now, we can plug s

we can set perimeter=184
we get

now, we can solve for y

we can isolate y on any one side


so, we get
...........Answer
So 3 pies with 8 pcs each.
8 x 3 = 24
3/4 of 24 is 18
the awnser is 18
Angle a +angle b = 180 degrees
angle a + angle a + 30 = 180
2*angle a = 150
angle a = 75degrees
angle b = 75+30 = 105 degrees
now, angle b +angle c = 180
so, angle c = 180-105 = 75 degrees
You need to use the cosine for this and this is how you do it.
Answer:
<u>-10x (1 - y)</u>
Step-by-step explanation:
<u>Given :-</u>
Side 1 = (2x + 5xy)
Side 2 = (-7x - 10xy)
<u>To Find :-</u>
Perimeter
<u>Formula :-</u>
Perimeter (rectangle) = 2 (Side 1 + Side 2)
<u>Solving :-</u>
Perimeter = 2 (2x + 5xy - 7x - 10xy)
= 2 (-5x - 5xy)
= <u>-10x (1 - y) => [Solution]</u>
