Answer:
18 cm
Step-by-step explanation:
The perimeter of a rectangle is given by the formula ...
P = 2(L +W)
Fill in the given information and solve for the width.
90 = 2(27 +W)
45 = 27 +W . . . . . divide by 2
18 = W . . . . . . . . . subtract 27
The width of the rectangle is 18 cm.
Answer:
6 m by 8 m
Step-by-step explanation:
The sum of two adjacent side lengths is half the perimeter, so is 14 meters. Two numbers differing by 2 that have a sum of 14 are half that total plus or minus have the difference: 7 ±1 = 6 and 8.
The room is 6 meters wide and 8 meters long.
87 numbers do not contain the digit 9
Answer:
y + 4 = -3(x + 1)
Step-by-step explanation:
point-slope form : y - y2 = m (x - x2)
In this case m = -3 and x2 = -1, y2 = -4
So
The equation in point-slope form
y + 4 = -3(x + 1)
