Answer:
2y-4-6y-12=4
-4y=20
y= -5
Step-by-step explanation:
because (y+2)(y-2)=y^2-4
so we have the step to let the every part have the same denominator y^2-4
2(y-2)/(y+2)(y-2) -6(y+2)/(y-2)(y+2)=4/(y-2)(y+2)
the denominators are the same so the equality .we just need the part over be the same 2y-4-6y-12=4
y= -5
Answer:
1380 in²
Step-by-step explanation:
The lateral surface is the sum of the areas of all the sides, or 'faces'.
The bases (the top and bottom) are <u>not </u>included.
This is a prism with triangles for bases (at each end). The sides are rectangles.
Add up the areas of the rectangles.
300 + 480 + 600 = 1380
The represent for that would be 572
Just plug in 100 for x
2(100)+1
200+1
Answer
201
and then for 25
2x+1=25
2x=24
Answer
X=12
35x + 20y = 7620
x+y=276
Y=276-x
35x+20(276-x)=7620
35x+5520-20x=7620
15x=2100
X=140
140+y=276
Y=136
140 adults and 136 children
