Answer:
For the diagram to be a parallelogram, then the measure of x is 4
Step-by-step explanation:
If the diagram is a parallelogram, then the diagonals bisect each other
What this mean is that they divide each other into 2
Mathematically, this means that the values AC is divided into two equal parts AE and CE
That means;
5x + 28 = 3x + 36
5x-3x = 36-28
2x = 8
x = 8/2
x = 4
The park is 2.25 km away, and Dave can travel .15 km per minute. Divide 2.25 by .15 to get how many minutes it will take him to get to the park. 2.25/.15 = 15. It will take Dave 15 minutes to get to the park.
Answer:
Width = 12 cm
Length = 14 cm
Step-by-step explanation:
Rectangle:
Let the width = x cm
So, the length = (x+2) cm
Perimeter = 52 cm
2 *(l+b) = 52
2 *(x+2 + x) = 52
2 * ( 2x + 2) = 52
2x + 2 = 52/ 2
2x + 2 = 26
2x = 26- 2
2x = 24
x = 24/2
x = 12
Width = 12 cm
Length = 14 cm
Answer:
Step-by-step explanation:
surface area=2×l×b+2(l+b)×h=2(lb+lh+bh)
=2(6×2+6×4+2×4)
=2(12+24+8)
=2×44
=88 square units.
