Factorise:<br> 3x3-3x2y+xy2-x2y

qaws [65]

$3x^3-3x^2y+xy^2-x^2y$

All terms have an x in them, so you factor that out first to get

$x(3x^2 -4xy+y^2)$

Now the 2nd degree equation will be of the form (3x- ... y)(x- ... y) and by just trying you find that the ... is just 1. So the factorization is:

$x(3x - y)(x - y)$

Answer:

300 g

Step-by-step explanation:

The problem statement tells us ...

36g = 0.12×d . . . . . where d represents the daily value

36g/0.12 = d = 300g . . . . divide by the coefficient of d

300 g of carbohydrates per day are recommended.

a trapezoid has one base of 10 inches,an altitude of 6 inches and an area of 51 square inches, find the length of the other base

Inessa [10]

$\bf \textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} a,b=\stackrel{bases}{parallel~sides}\\ h=height\\ ---------\\ a=10\\ h=6\\ A=51 \end{cases}\implies 51=\cfrac{6(10+b)}{2} \\\\\\ 51=3(10+b)\implies \cfrac{51}{3}=10+b\implies 17=10+b\implies 7=b$

The radius of a cylindrical water tank is 5.5ft, and its height is 13ft. What is the volume of the tank?

svetlana [45]

Answer:

The volume of the tank is 1235ft³

Step-by-step explanation:

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 13ft

π = 3.14

r = radius = 5.5ft

v = (π * r²) * h

we replace the unknowns with the values we know

v = (3.14 * (5.5ft)²) * 13ft

v = (3.14 * 30.25ft²) * 13ft

v = 94.985ft² * 13ft

v = 1234.805ft³

Round to the nearest whole number

v = 1234.805ft³ = v = 1235ft³
