What number must be squared in order to complete the pattern. 49,64,81,100

Can someone help me with my math homework I don't get it and can you please explain how you did it. Also only help me with the h

1) What you see as 3 $\frac{3}{8}$ can be also changed to only a fraction, by changing $\frac{3}{1}$ to $\frac{24}{8}$ , but since the question wants 2 as a whole number, we must take out $\frac{24}{8} = 2 \frac{8}{8}$ and then add the 8 eights to the other 3, to get <span> $2 \frac{11}{8}$

</span>for # 10- 13, you need to have the same number on the bottom of all the numbers being subtracted, that means turning the number that aren't fractions (like 4) into fraction, and then into fractions with the same denominators.

10) $\frac{4}{1}$ changes to $\frac{32}{8}$ to get $\frac{32}{8} - \frac{3}{8} = \frac{29}{8}$ or $3\frac{5}{8}$

11) $\frac{5}{1}$ changes to $\frac{50}{10}$ , and $2\frac{3}{10}$ to $\frac{13}{10}$ to get $\frac{50}{10}-\frac{13}{10}=\frac{37}{10}$ or <span> $3\frac{7}{10}$ </span>

If f(x) = 3x + 2 and g(x) = x2 + 1, which expression is equivalent to (fog)(x)?

Vedmedyk [2.9K]

Answer:

3(x² + 1) + 2

Step-by-step explanation:

(f ○ g)(x) = f(g(x))

Substitute x = g(x) into f(x), that is

f(x² + 1) = 3(x² + 1) + 2 ← is the equivalent statement

a square painting has an area of 81x^2-90x-25. A second square painting has an area of 25x^2+30x+9. What is an expression that r

galina1969 [7]

Answer:

The answer in the procedure

Step-by-step explanation:

Let

A1 ------> the area of the first square painting

A2 ----> the area of the second square painting

D -----> the difference of the areas

we have

$A1=81x^{2}-90x-25$

$A2=25x^{2}+30x+9$

case 1) The area of the second square painting is greater than the area of the first square painting

The difference of the area of the paintings is equal to subtract the area of the first square painting from the area of the second square painting

D=A2-A1

$D=(25x^{2}+30x+9)-(81x^{2}-90x-25)$

$D=(-56x^{2}+120x+34)$

case 2) The area of the first square painting is greater than the area of the second square painting

The difference of the area of the paintings is equal to subtract the area of the second square painting from the area of the first square painting

D=A1-A2

$D=(81x^{2}-90x-25)-(25x^{2}+30x+9)$

$D=(56x^{2}-120x-34)$

Barney's Book Store currently has 2000 books in stock. There are 3 times as many non-fiction books as fiction books. Determine t

xxMikexx [17]

Answer:

There are 1500 non fiction books and 500 fiction books currently in the store.

Step-by-step explanation:

Given:

Total Number of books = 2000

Let the number of fiction books be 'x'.

Now given:

There are 3 times as many non-fiction books as fiction books.

Number of non fiction books = $3x$

We need to find the number of non-fiction and fiction books.

Solution:

Now we know that;

Total Number of books is equal to sum of the number of non-fiction and fiction books.

framing in equation form we get;

$x+3x=2000\\\\4x=2000$

Dividing both side by 4 we get;

$\frac{4x}{4}=\frac{2000}{4}\\\\x= 500\ books$

Number of fiction books = 500

Number of non fiction books = $3x=3\times 500 =1500$

Hence There are 1500 non fiction books and 500 fiction books currently in the store.
