Answer:
A. 6x + 4
B. 22 cm
Step-by-step explanation:
The perimeter of the triangle is equal to the sum of all the side lengths, which is (2x+3) + (x+1) + (3x), or 6x + 4.
When x = 3cm, the perimeter is 6(3) + 4, which is 22 cm.
X=12
This is because you subtract 6 from both sides to get the x isolated.
So x=18-6
x=12 :)
Answer:
19 degrees, 70 degrees, 91 degrees
Step-by-step explanation:
to make an interior angle of a triangle you need to make a 180-degree triangle and 19+70+91 make 180 degrees
Answer:
5/3
Step-by-step explanation:
To find the slope we pick one set of points
2/3,-1/2
Set your equation up like this
y2-y1/x2-x1
Plug in and subtract(notice the negative)
And we get 5/3
Hope this helps
