Please help!! (Number 73)
Rasek [7]
So hmm notice the picture below

one is 7x5x1.75 the volume of a rectangular prism is V = length * width * height

so 7*5*1.75 gives us 61.25 ft³

the second one, is larger by some width and length we dunno, but we know that it required that 61.25 plus an extra 17.5 to fill it up, so its volume is 61.25 + 17.5 or 78.75

the height is the same... so \bf V=l\cdot w\cdot h\qquad &#10;\begin{cases}&#10;l=length\\&#10;w=width\\&#10;h=height\\ --------\\&#10;h=1.75\\&#10;V=78.75&#10;\end{cases}\implies 78.75=lw\cdot 1.75&#10;\\\\\\&#10;\cfrac{78.75}{1.75}=lw\implies 45=lw

so.. if you factor 45, to two factors, one will be the length, the other the width

Find all the zeros help please
iren [92.7K]

With f(7) = 0, you know that f(x) is divisible by x-7. So

f(x) = (x-7)(ax^2+bx+c) \\\\ x^3-4x^2-25x+28 = ax^3+(b-7a)x^2+(c-7b)x-7c \\\\ \implies \begin{cases}a=1\\b-7a=-4\\c-7b=-25\\-7c=28\end{cases} \implies a=1,b=3,c=-4

Then we have

f(x)=(x-7)(x^2+3x-4)=(x-7)(x+4)(x-1)

which makes the zeros 7, -4, and 1.

Answer:

the answer is 4x-3x^2

Step-by-step explanation:

since you cant combine like terms, the binomial is already simplified

if you want to factor it, the binomial would be rewritten as x(4-3x)
