Answer:
Width = 16 cm
Length = 12 cm
Step-by-step explanation:
Let the width of the rectangle be represented as x
Width = x cm
Length = (x - 4) cm
Area = L*W = 192 cm²
Thus:
x * (x - 4) = 192
x² - 4x = 192
x² - 4x - 192 = 0
Factorize
x² - 16x + 12x - 192
x(x - 16) +12(x - 16)
(x - 16)(x + 12)
x = 16 or x = -12
Width cannot be a negative number, therefore, the width of the rectangle = x = 16 cm
Width = x = 16 cm
Length = (x - 4) cm = (16 - 4) = 12 cm
Answer:
Step-by-step explanation:
we know that
If line l is parallel to line m
then
-----> by supplementary angles (consecutive interior angles)
solve for x
Use Power of a Point; 180-60=120º
Answer:
Step-by-step explanation:
I think you wanted a graph...
The y-intercept is the only part of the y axis where the line passes through.
So the slope is 1/3 -- rise/run
So from -1 on the y axis, go up 1 and right 3
keep going until you run out of space and make a line.
The approximate circumference of the circle with the diameter of 300 feet, would be C. 942 feet. Since C = Pi • diameter = 3.14 • 300 which would be about 942 feet.
