2 equations, 2 unknowns. Call height H and base B.
From the first sentence:
HB = 216
From the second sentence:
H = ⅔ B
Plug the second into the first and solve for B:
(⅔ B)B = 216
B^2 = 324
B = 18
Plug that back into either of the original 2 equations and solve for H:
H(18) = 216
H = 12
Answer:
4.2
Step-by-step explanation:

Answer:
700cm
Step-by-step explanation:

Answer:
4 4/5
Step-by-step explanation:
Answer:
-¼x + y = -2
Step-by-step explanation:
First, convert to Slope-Intercept Form by moving "1" to the other side of the equivalence symbol to get <em>y</em><em> </em><em>=</em><em> </em><em>¼x</em><em> </em><em>-</em><em> </em>2, then finally convert to Standard Form by moving "-¼x" to the other side of the equivalence symbol to end up with <em>-¼x + y = -</em>2.
