Answer:
answer = 21
Step-by-step explanation:
2n - 2 = 40
2n - 2 + 2 = 40 + 2
2n = 42
2n/2 = 42/2
n = 21
Y-y1=m(x-x1)
find slope
(y2-y1)/(x2-x1)
so
(-4,-1)
(3,-3)
slope=(-3-(-1))/(3-(-4))=(-3+1)/(3+4)=-2/7
y-(-1)=-2/7(x-(-4))
y+1=-2/7(x+4)
It is 0.575000. All you have to do is divide the numerator by the denominator.
For this problem you need to find the area.
To find area, you multiply the width by the length.
You multiply 12 1/2 by 5 1/2 and you get 31 1/4
This is how you do it::
= 25/2 × 5/2
= (25 × 5) / (2 × 2)
= 125/4
= 125/4
<span>= 31 1/4
So you know that the area is 31 1/4 yards.
In the question it asks HOW MANY FEET so we have to convert 31 1/4 yards to feet.
1 yard= 3 feet
31 1/4 *3= </span><span>93.75
<span>John need to buy 93.75 feet of fencing to enclose the area.</span></span>
Answer:
120
Step-by-step explanation:
Angles opposite to equal sides are equal .
30 + 30 + x = 180 {Angle sum property of triangle}
60 + x = 180
x = 180 - 60
x = 120
