The simplest expression is (2w)+(2*3w), because to calculate perimeter, you have to use this formula: 2length+2width.
Let the width = X, then the length would be 5x ( 5 times as long as the width).
The perimeter is adding the 4 sides.
x + x + 5x + 5x = 70
Combine the like terms:
12x = 70
Divide both sides by 12:
x = 70/12
x = 5.83
The width = 5.83 cm.
The length = 5 x 5.83 = 29.15
Now round each length to the nearest tenth:
5.8 and 29.2 cm.
The answer is d.
First you need to simplify the equation.
y + 3 = 2(x - 1)
y + 3 = 2x - 2
Then you need to put that into slope-intercept form (y = (slope)x + (y intercept))
y + 3 = 2x - 2
-3 -3
y = 2x - 5
The slope is the coefficient of x, so 2 is the slope of the line.
To reflect a triangle, just draw the opposite of what it originally looked like, aka mirror image.
