Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:
(
−
1
,
9
)
Equation Form:
x
=
−
1
,
y
=
9
(2x - y)(4x2 + 2xy + y2) =
8x3 + 4x2y + 2xy2 - 4xy2 - 2xy2 - y3 (combine and simplify like terms)
= 8x3 - y3
Answer:
785.0cm³
Step-by-step explanation:
Formula of calculating volume of a cylinder
= π r²h (Pie × radius square × height)
Radius given = 5cm
Height given = 10cm
working: π × radius²× height
= π × 5² × 10
=785.5398
=785.0cm³ (3s.f)
Multiply .33x6=1.98
this will give you the number of liters
