4e+5f=9
A.(2,2)
B.(1,1)
C.(,1,-1(
D.(-2,-2)
E.IMS
F,NS
1 answer:
5e + 4f = 9....multiply by -4 4e + 5f = 9 ...multiply by 5 ------------------ -20e - 16f = -36 (result of multiplying by -4) 20e + 25f = 45 (result of multiplying by 5) ----------------add 9f = 9 f = 9/9 f = 1 5e + 4f = 9 5e + 4(1) = 9 5e + 4 = 9 5e = 9 - 4 5e = 5 e = 5/5 e = 1 solution is (1,1)

Answer:
158 m²
Step-by-step explanation:
Get the area of all the faces, then add them
