Answer:

Hello, i think to work this equation out is you have to add 42 on 42 they cancel and you add 42 on the other side so then the answer is 45

Answer:

(p-3)(p+14)

Step-by-step explanation:

factors of 42:

1 x 42

2 x 21

3 x 14

6 x 7

The only pair that would work are -3 and 14

write the ratio as a fraction in simplest form. with whole numbers in the numerato and denominator. 40g : 64g

babunello [35]

Answer:

$\frac{5g}{8g}$ OR 5g : 8g

Step-by-step explanation:

Also a ratio can also be represented by a fraction; $\frac{40g}{64g}$

So to make the ratio to the simplest form we have to divide by a number that can divide both number.

40g : 64g

We can start dividing by 2 which will give us;

20g : 32g

$\frac{20g}{32g}$

Now we can divide by 2 again since it can divide both numbers which will give us;

10g : 16g

$\frac{10g}{16g}$

We can still divide by 2 since it can divide both numbers which will give us;

5g : 8g

$\frac{5g}{8g}$

Since no numbers can divide 5 and 8 equally that is our answer.

Also, $\frac{5g}{8g}$

Answer:

see below

Step-by-step explanation:

All of the given data sets have x-values that are sequential with a difference of 1. That makes it easy to determine the sort of sequence the y-values make.

first choice: the y-values have a common difference of -2. This will be matched by a linear model.

second choice: the y-values have a common difference of +2. Again, this will be matched by a linear model.

third choice: the y-values have a common ratio of -2. This will be matched by an exponential model.

fourth choice: the y-value differences are 3, 5, 7, increasing by a constant amount (2). This is characteristic of a sequence that has a quadratic model.
