Hi there!
If KLM is an isosceles triangle, then KM = LM.
4d - 13 = 12 - d
Solve for d. Add 'd' to both sides:
5d - 13 = 12
Add 13 to both sides:
5d = 25
Divide both sides by 5:
<u>d = 5 units.</u>
Answer:
19 m
Step-by-step explanation:
Perimeter = 2(length + width) ; P = 2(l+w) - - (1)
Area = Length * width ; A = l*w - - - (2)
76 = 2(l+w)
76/2 = l+w
l+w = 38
l = 38 - w
Put l = 38 - w in (1)
A = (38-w)*w
A = 38w - w²
At maximum point:
dA/dw = 0
dA/dw = 38 - 2w
38 - 2w = 0
38 = 2w
w = 38/2
w = 19
310-85=225
225/25=9
Therefore it will take her 9 weeks
The perimeter is 10 try to draw these points on the graph and count the distance between each or you can just look at the coordinates and find the distance and then add length and width
Answer:
Step-by-step explanation:
sin x = opp/hyp
sin(52) = 18/z
z = 18/sin(52)
z = 22.84
