Step-by-step explanation:
Perimeter is all the sides added up together.
Divide 16 by 2, so that you can get just a measurement of the length and the width.
16/2 = 8
Since the length is 5.25, subtract that by 8.
8-5.25 = 2.75
The width of the phone is 2.75 inches.
Answer:
6s(5k+3)
Step-by-step explanation:
18s+30sk
Factor out 6.
6(3s+5sk)
Consider 3s+5sk. Factor out s.
s(3+5k)
Rewrite the complete factored expression.
6s(5k+3)
Answer:
y=30
x=60
Step-by-step explanation:
The triangle has all sides equal therefore all the angles are equal.
For all the angles to be equal and add up to 180 (sum of angles in a triangle is 180), each angle has to be 60.
Therefore y=90-60
=30
x=180-(30+90)
=60
Answer:
The equation of the line would be y = 4/9x
Step-by-step explanation:
In order to find the equation, we first need to find the slope. We can do this by using the slope equation with the points.
m(slope) = (y2 - y1)/(x2 - x1)
m = (9 - 0)/(4 - 0)
m = 9/4
Now that we have this, we can use point-slope form along with one of the points to get the equation.
y - y1 = m(x -x1)
y - 0 = 4/9(x - 0)
y = 4/9x
