Answer:
length of each side : 10 cm
Step-by-step explanation:
all sides of squares are equal
thus, 4 sides = 40 cm
1 side = 40/10 cm
1 side = 10 cm
Answer:
There are no real roots for this equation.
Step-by-step explanation:
The only solution is irrational: x-√(4-8x)=0
I have provided a graph to help you with this problem.
Hope this helps! :)
Step-by-step explanation:
Im not sure if its supposed y = -2x + 1 or y = 2x + 1 but I'll solve the problem for both.
First for y = -2x + 1
Since the line has to be parallel to y = -2x + 1
the slopes would be the same.
so, so far the equation would be
y = -2x + b
now we substitute (5,2) into the equation
2 = -2(5) + b
2 = -10 + b (Add 10 to both sides of the equation)
+10 +10
12 = b
Now that we solved for b
The equation would be
y = -2x + 12
^^ This equation is parallel to y = -2x + 1
Now to solve for an equation parallel to y = 2x + 1
Both equations would have the same slope
So far we would have
y = 2x + b
Now we solve for be by substituting the point (5,2)
2 = 2(5) + b
2 = 10 + b (subtract 10 from both sides)
-10 -10
-8 = b
After solving for b
The equation is
y = 2x - 8
This equation is parallel to y = 2x + 1
Total length of the trim painted is 15.75 unit.
<u>Given:</u>
- Co-ordinate of point A = (-2,4)
- Co-ordinate of point B = (2,2)
- Co-ordinate of point C = (-1,-2)
<u>Find:</u>
<em>Total length</em> of the trim painted
<u>Computation:</u>
Distance between two point = √(x1 - x2)² + (y1 - y2)²
Distance between AB = √(-2 - 2)² + (4 - 2)²
Distance between AB = √16 + 4
<em>Distance between AB</em> = 2√5 unit = 4.47 unit
Distance between BC = √(2 + 1)² + (2 + 2)²
Distance between BC = √9 + 16
<em>Distance between BC</em> = 5 unit
Distance between AC = √(-2 + 1)² + (4 + 2)²
Distance between AC = √1 + 36
<em>Distance between AC</em> = √37 unit = 6.08 unit
Total length of the trim painted = 4.47 + 5 + 6.08
Total length of the trim painted = <em>15.75 unit (Approx.)</em>
