Step-by-step explanation:

a.

y = kx \\ 21 = k \times 3 \\ 21 \div 3 =  \frac{(k \times 3)}{3}  \\ 7 = k

b.

y = kx \\ 24 = k \times 4 \\  \frac{24}{4}  =  \frac{(k \times 4)}{4}  \\ 6 = k

Factor x^4 + xy^3 + x^3 + y^3. Hint, first factor a monomial. Please explain why!!!
almond37 [142]

Pull an x from the first two terms

x(x^3 + y^3) + (x^3 + y^3)   Now x^3 + y^3 is a common factor.

(x^3 + y^3)*(x + 1) That should be far enough. It can be factored further by factoring (x^3 + y^3) but there is no point because you can't do anything after that. But in case you want to know how x^3 + y^3 factors

(x^3 + y^3) = (x + y)(x^2 - xy + y^2)

Which means you could write original polynomial as

(x + y)(x^2 - xy + y^2)(x + 1)

Part B

You factored the x out of xy^3 so that you would have a common factor (x^3 + y^3) to pull out as a common factor for the whole polynomial.

Need help plzz I am struggling
otez555 [7]

The equation you need to find x is,

12x^{\circ}+30^{\circ}=90.

Then solving for x gives you x=5.

Hope this helps.
