Let a= x^2 +4. Rewrite the following equation in terms of a and set it equal to zero.
swat32

Answer:

C and G

Step-by-step explanation:

(x^2+4)^2+32=12x^2+48 is written as (x^2+4)^2+32=12x^2+48.

We can simplify the expression using the term a by replacing x^2 + 4 with a.

(x^2+4)^2+32=12x^2+48\\(x^2+4)^2+32=12(x^2+4)\\a^2 + 32 = 12a\\a^2 - 12a + 32 = 0

This factors into (a-4)(a-8). Solve by setting each factor equal to 0 and solve for a.

a-4 = 0                 a=4

a-8=0                   a=8

prisoha [69]

Answer:

\frac{8}{25}

Step-by-step explanation:

probability of selecting a girl from students is \frac{4}{5}

probability of girl wearing sneaker from girls is \frac{4}{10} or \frac{2}{5}

hence, probability of selecting a girl wearing a sneaker will be,

⇒ probability = probability of delecting a girl from students × probability of girl wearing sneakers from girls

⇒ probability = (\frac{4}{5})( \frac{2}{5})

⇒ probability = \frac{8}{25}

Michelle has a maximum of 4500 milliliters  of water for her plants today. Each basil plant requires 350 of water, and each fenn
anyanavicka [17]

The inequality becomes :

350B+525F≤4500

Explanation:

Let the number of basil plants be represented by = B

Let the number of fennel plants be represented by = F

As each basil plant needs 350 ml of water, so B basil plants will need 350*B = 350B ml of water

Similarly, each fennel plant needs 525 ml of water so F fennel plants will need 525*F = 525F ml of water.

And both the plants need to be watered with a maximum of 4500 ml of water.

So inequality becomes: 350B+525F≤4500
