Divide the perimeter by 2, this will give you the sum of one length and one width.
68/2 = 34 yards
Now the length is 10 yards more, so subtract 10 from the 34 and divide by 2 again:
34 - 10 = 24
24 /2 = 12
The width is 12 yards.
The length is 12 + 10 = 22 yards.
Answer:
<h3>
</h3>
Step-by-step explanation:
y= x²+6x-5
completing the square: <em> a²+2ab+b²</em> <em>= (a+b)²</em> where <em>a²=x² </em>(so <em>a=x</em>) and <em>2ab=6x </em> (so <em>b</em> would be 3):
Answer:
Step-by-step explanation:
now the equation looks like
3-4Cos(x)=y
hmmm i'm wondering if you can figure it out from here??? it's the same as the other two.. plug in that 
/2 .. can you? :)
Answer:
i think the perimeter is 31 m
Step-by-step explanation:
Answer:
It is a rectangle.
LENGTH = 5 X+2 IF X = 5 L = 5×5+2 =25+2=27
L=27
BREADTH = X+8 IF X=5 B =5+8= 13
B= 13
Area of the rectangle = L× B
=27×13
= 351
Perimeter of the rectangle=2(l+b)
=2(27+13)
=2×40
=80
