How do u find the lcf

Mathematics
1 answer:
olya-2409 [2.1K]4 years ago
8 0

Step-by-step answer:

The fastest way is to factor the given expression, either by inspection or grouping.

We write

3x^2+10x+3 ..........................................(1)

= (3x^2+x)+9x+3

= x(3x+1) + 3(x+1)

=(x+3)(3x+1)

so (3x+1) is a factor.

We can also eliminate the two other factors by observing

(3x+3) = 3(x+1), but 3 is not a common factor in (1), so this can be eliminated.

(3x-1) has a negative sign, but (1) does not have ANY negative sign, so again this can be eliminated.  That leaves (3x+1) as the only possibility.  Again, factoring confirms that it is.

A small-appliance manufacturer finds that the profit P (in dollars) generated by producing x microwave ovens per week is given b
Olegator [25]

Answer:

Number of ovens must be manufactured in a given week to generate a profit of $1610  is 70

Step-by-step explanation:

We are given

A small-appliance manufacturer finds that the profit P (in dollars) generated by producing x microwave ovens per week is given by the formula

P=\frac{1}{10}x(300-x)

provided that 0 ≤ x ≤ 200

We are given

profit is $1610

so, we can set P=1610

and then we can solve for x

1610=\frac{1}{10}x(300-x)

Multiply both sides by 10

1610\cdot \:10=\frac{1}{10}x\left(300-x\right)\cdot \:10

16100=x\left(300-x\right)

16100=300x-x^2

-x^2+300x-16100=0

now, we can factor it

(x-70)(x-230)=0

we can solve for x

and we get

x=70,x=230

Since, x=230 does not lie on 0 ≤ x ≤ 200

So, we will consider only x=70

So,

Number of ovens must be manufactured in a given week to generate a profit of $1610  is 70
