Each week Charlene uses 3/4 of a bag of cat food to feed her cats. She has 112 bags of cat food in stock. How long will her stoc

inessss [21]

The stock of cat food will last for 149 weeks.

Step-by-step explanation:

Given,

Bags of cat food in stock = 112

Bags used each week = $\frac{3}{4}\ of\ one\ bag$

Let,

x be the number of weeks.

Therefore,

$\frac{3}{4}x=112$

Multiplying both sides by 4/3

$\frac{4}{3}*\frac{3}{4}x=112*\frac{4}{3}\\x=\frac{448}{3}\\x=149.33$

Rounding off to nearest whole number;

x=149

The stock of cat food will last for 149 weeks.

Factor completely 2x3 + 8x2 + 3x + 12.

goblinko [34]

Answer:

$(2x^2+3)(x+4)$ .

Step-by-step explanation:

$2x^3+8x^2+3x+12$

We need to find the factors of given equation;

Solution:

On Solving the above equation we get;

Now First we will take common factor from first 2 terms which is $2x^2$ we get;

$2x^2(x+4) + 3x+12$

Now we will take the common factor from the last 2 terms which is 3 we get;

$2x^2(x+4) + 3(x+4)$

Here we get 2 terms in which $(x+4)$ is common factor.

$(x+4)(2x^2+3)$

Hence After factorizing the given equation we get $(2x^2+3)(x+4)$ .
