Answer:
-5/3
Step-by-step explanation:
(3x+5)(3x+5) is the factored form of the quadratic: 9x^2+30x+25
In equation form, it will be 9x^2+30x+25 = 0 so we have:
(3x+5)(3x+5) = 0
To solve these types of equations, we find the roots. Since the product of these numbers is 0, (3x+5) has to be equal to 0.
3x + 5 = 0
Subtract 5
3x = -5
Divide by 3
x = -5/3
The error is that 15 was subtracted on the left side when it should’ve been added.
Corrected equation:
27 = n-15
Add 15 to both sides
42 = n
Since each point of the triangle is going to be 1.5 times as far from the center of dilation, each side will increase by a factor of 1.5..
3 x 1.5 = 4.5m
4 x 1.5 = 6m
5 x 1.5 = 7.5m
So the perimeter of the new triangle will be 4.5 + 6 + 7.5 = 18 meters
Neither. They can’t be parallel because both lines have different slopes. They aren’t perpendicular either because their slopes don’t multiply to equal -1.
Radius = 24.49
Hope this helps! (If not sorry!)
