A health food company makes its 'Superfood Blend' from whey protein, which costs $10.25 per pound, and powdered spirulina, which
kaheart [24]

Given:

Cost of protein = $10.25 per pound

Cost of spirulina = $22.45 per pound

Cost of blend = $16.35 per pound

Weight of blend = 140 pounds

To find:

The quantity of spirulina it will need to make the blend.

Solution:

Let x be the quantity of protein and y be the quantity of spirulina in the blend. Then,

x+y=140                      ...(i)

Equation (i) can be written as:

x=140-y                      ...(ii)

10.25x+22.45y=16.35\times 140

10.25x+22.45y=2289                  ...(iii)

Using (ii) and (iii), we get

10.25(140-y)+22.45y=2289

1435-10.25y+22.45y=2289

12.2y=2289-1435

12.2y=854

Divide both sides by 12.2.

y=\dfrac{854}{12.2}

y=70

Therefore, 70 pounds of the spirulina it will need to make the blend.

Sari is factoring the polynomial 2x2 + 5x + 3. What is the missing number in her factorization?
babymother [125]

Answer:

the factor of polynomial 2x^{2}+5x+3 is =\left(x+1\right)\left(2x+3\right)

Step-by-step explanation:

We need to factor the polynomial 2x^{2}+5x+3

Break the expression into groups,

=\left(2x^2+2x\right)+\left(3x+3\right)

\mathrm{Factor\:out\:}2x\mathrm{\:from\:}2x^2+2x\mathrm{:\quad }

\mathrm{Apply\:exponent\:rule}:\quad \:a^{b+c}=a^ba^c

x^2=xx

then

2x^2+2x=2xx+2x

\mathrm{Factor\:out\:common\:term\:}2x

=2x\left(x+1\right)

\mathrm{Factor\:out\:}3\mathrm{\:from\:}3x+3\mathrm{:\quad }3\left(x+1\right)

=2x\left(x+1\right)+3\left(x+1\right)

\mathrm{Factor\:out\:common\:term\:}x+1

=\left(x+1\right)\left(2x+3\right)

Hence, the factor of polynomial 2x^{2}+5x+3 is =\left(x+1\right)\left(2x+3\right)
