Answer:
Step-by-step explanation:
P = 2(L + W).....perimeter of a rectangle formula
P = 20
L = 2W + 1
20 = 2(2W + 1 + W)
20 = 2(3W + 1)
20 = 6W + 2
20 - 2 = 6W
18 = 6W
18/6 = W
3 = W <==== the width is 3 inches
L = 2W + 1
L = 2(3) + 1
L = 6 + 1
L = 7 <===== the length is 7 inches
For a clock wise rotation the coordinates will change from(x,y) to (-x,y). The negative sign means opposite by the way.
Distance = speed x time
Speed= 520÷10=52
52mi/hour
Answer:
x = 25
Step-by-step explanation:
Solve by isolating x:
(x-7)2 = 36
x-7 = 18
x = 25
0.13 + 0.14= 0.27
0.27 ÷ 2 = 0.135
Therefore the midpt. Is 0.135
