Answer:
5 meters
Step-by-step explanation:
The perimeter of a rectangle can be expressed as 2l+2w.
2l+2w=50
l=w+15
Substitute:
2(w+15)+2w=50
2w+30+2w=50
4w+30=50
4w=20
w=5

Answer:
b. six equilateral triangles
Step-by-step explanation:
The 6 interior angles of the hexagon are supplementary to the exterior angle and are 120 deg. ... Therefore the angles at the center is 360/6 = 60 degrees for each triangle. So all three angles of the six triangles are 60 deg each. So there are 6 equilateral triangles that form the regular hexagon.
Answer:
Let x = cube root of 400
Using a calculator x = 7.368 to 3 decimal places
So: 7 < x < 8
Answer:The second one to the right is 50 because 5 times 5 is 25 and the other is 5 times 5 to and 25 plus 25 is 50.The 2 one on the right is 40 is you multiply the length times width which is the area of a rectangle and square so do that for all of them and you find the answer for x by determining whats the length and width based on the known answers already
Step-by-step explanation:
