Answer:

3x² - 21x + 30

Step-by-step explanation:

y = 3(x - 5)(x - 2) ← expand factors using FOIL

  = 3(x² - 7x + 10) ← distribute parenthesis by 3

y = 3x² - 21x + 30 ← in standard form

Komodo dragons are the heaviest lizards on earth. A baby Komodo dragon is 1 3/4 feet long when it hatches. It’s mother is 8 3/4
sukhopar [10]

Answer:

An adult male Komodo dragon is 10\frac12 feet.

Therefore the male is 1\frac34 feet longer than the mother.

Step-by-step explanation:

Given that,

A baby dragon is 1\frac34 feet long.

It's mother is 8\frac34 feet.

An adult male Komodo dragon is 6 times as long as the baby Komodo dragon.

So, an adult male Komodo dragon is =(6×1\frac34 ) feet

                                                          =6\times \frac74 feet

                                                          =\frac61\times \frac74 feet

                                                         = \frac {21}2 feet.

                                                         =10\frac12 feet.

\therefore 10\frac 12- 8\frac34

=\frac{21}{2}-\frac{35}4

=\frac{21\times 2-35\times 1}{4}

=\frac{42-35}{4}

=\frac74

=1\frac34

Therefore the male is 1\frac34 feet longer than the mother.

Sally bought some candy bars for $1.25 each and some sodas for $1.49 each. If she bought a total of 38 items and spent $50.38 ho
hammer [34]

Answer:

26 candy bars and 12 sodas

Step-by-step explanation:

This problem can be solved by a simple system of equations

I am going to call x the number of candy bars that Sally bought and y the number of sodas that Sally bought.

The fact that she bought 38 itens means the x + y = 38.

She spent $50.38. The value she spent is the sum of the number of candy bars multplied by the value of the candy bar and the number of sodas multiplied by value of a soda. So 1.25x + 1.49y = 50.38

So we have to solve the following system:

1)x + y = 38

2)1.25x + 1.49y = 50.38

From 1), we have that x = 38 - y. I am going to replace it in 2)

1.25(38-y) + 1.49y = 50.38

-1.25y + 1.49y = 50.38 - 47.5

0.24y = 2.88

y = 12.

Sally bought 12 sodas.

In 1: x = 38-y = 38-12 = 26

Sally bourght 26 candy bars
