"one half" = \frac{1}{2}
Your problem becomes  this but you don't have to do this method to solve this problem: \frac{1}{2} * \frac{2}{1} * \frac{25}{1}. So,
\frac{1}{2} ( \frac{2}{1} ) ( \frac{25}{1} )  \\  \frac{1}{2}  ( \frac{2}{1} )  = 1  \\  \frac{1}{1} ( \frac{25}{1} ) =  \frac{25}{1}   \\ Answer: 25

If f(x)= 2x^2 -4x and g(x) = 5 – 2x, evaluate f(x) – g(x) for x = 5
Orlov [11]
<span>If f(x)= 2x^2 -4x and g(x) = 5 – 2x, evaluate f(x) – g(x) for x = 5

you first plug in 5 for x in both equations...
(2(5)^2-4(5))=f(x)
5-2(5)=g(x)

now you evaluate...
(2(25)-20)-5-10
50-30-15
20-15=5

5

A food company originally sells cereal in boxes with dimensions 25 cm by 14 cm by 10 cm. To make more profit, the company decrea
hjlf

Answer:

1.75 cm

Step-by-step explanation:

We are given that the dimensions of the box as 25 cm by 14 cm by 10 cm.

Now, to increase the profit, the dimensions of the box by 'x' cm.

Thus, the new dimensions are (25-x) cm by (14-x) cm by (10-x) cm.

Further, it is given that the volume of the new box is 2,208 cm^{3}

As, Volume of the box = Length × Breadth × Height

i.e. 2208 = (25-x) × (14-x) × (10-x)

i.e. 2208 = (25-x) \times (140-24x-x^{2})

i.e. 2208=x^{3}-x^{2}-740x+3500

i.e. x^{3}-x^{2}-740x+1292=0

On solving this cubic equations, we get that, the solutions are x = 27.6, x = 1.75 and x = 26.8.

Since, the dimensions 25 cm by 14 cm by 10 cm are reduced by x cm.

Thus, if x = 27.6 or x = 26.8, then (10-x) = -17.6 or -16.8, which cannot be possible. So, x = 1.75 cm.

Hence, the dimensions were decreased by 1.75 cm.

3-2y-1+5x^2-7y+7+4x^2
MakcuM [25]

Answer: Hi!

The only thing we can do to simplify the equation is combine like terms.

5x^2 + 4x^2 = 9x^2

-2y - 7y = -9y

3 - 1 + 7 = 9

Our equation now looks like this:

9x^2 - 9y + 9

We have nothing left to simplify, so we're done!

Hope this helps!
