Someimes becasue either x or y could be obtuse.
The equation for the area of a triangle is 1/2 x base x height.
Plug in the values that you already have with h being the missing height value:
30= 1/2 x 12 x h
Simplify:
30=6h
Solve:
30/6=h
5=h
The heoght of the triangle is 5 units
Worded weird but I will try my best. I believe the expression would be: y = 12h + 20
Answer:
The Answer would be B.
Step-by-step explanation:
Rearrange
5+2*(3+2*x)-(x+3*(x+1))=0
Step 2:
(5 + 2 • (2x + 3)) - (4x + 3) = 0
Step 3 :
8 = 0
Step 4 :
Equations which are never true :
8 = 0
This equation has no solution.
The answer would be B, which is negative two.
