Step-by-step explanation:
height= 4b
length = 2 + b
volume = 60in³
or, l ×b × h = 60in³
or, (2+b) × b × 4b = 60in³
or, 4b²(2+b) = 60in³
or, 8b² + 4b³ = 60
or, 2b² + b³ = 15
or, b³ + 2b² -15= 0
b= 1.95
l= 2+1.95=3.95
h= 4×1.95 = 7.8
Answer:
x= -6,-12
Step-by-step explanation:
Answer:
c+b / a
option 4
Step-by-step explanation:
ax - b = c
add b to both sides
ax = c + b
divide a on both sides
x = c+b / a

Answer:
x = 2 and y = 5
Step-by-step explanation:
2x = 2
x = 2
-4 + y = 1
y = 5
