Answer:
20 yards
Step-by-step explanation:
Given that:
Two Given polygons are similar :
Ratio of corresponding sides =. 1/6
Perimeter of larger polygon = 120 yards
Perimeter of smaller = p
Since they are similar, and yhe ratio of their sides Given, we use the relation :
(Smaller perimeter / larger perimeter) = (smaller side / larger side)
(p / 120) = (1 /6)
Cross multiply :
6p = 120
p = 120/6
p = 20 yards
Answer:
B) P = 8x + 4
Step-by-step explanation:
Formula:
P= 2( l + w)
P = 2( x + 2 + 3x)
P = 2(4x + 2)
P = 8x + 4
Use linear combination to solve this. It is much faster than substitution. I would start by multiplying the bottom equation by -1.
<span>4x-7y=3
-x+7y=15</span>
Then, add the two equations together. The result is:
3x=18.
You've eliminated one variable. Now you can solve for the other one.
Divide both sides by 3 to get
x=6
Plug this into one of the original equations, then solve for y
-(6)+7y=15
7y=21
y=3
Check your work by plugging these values into both equations to see if they remain true
Answer:
Step-by-step explanation:
xy = 32
x ; y is the divisor of 32
but : 32 = 2^5
6 ordered pairs of positive integers satisfy xY=32
(1;32) , (2;16) , (4; 8),(32; 1) , (16;2) , (8;4) .
