Answer:

Let's solve for f.

Step 1: Multiply both sides by fr.

4f+8r=

5fr

Step 2: Multiply both sides by g.

4fg+8gr=5fr

Step 3: Add -5fr to both sides.

4fg+8gr+−5fr=5fr+−5fr

4fg−5fr+8gr=0

Step 4: Add -8gr to both sides.

4fg−5fr+8gr+−8gr=0+−8gr

4fg−5fr=−8gr

Step 5: Factor out variable f.

f(4g−5r)=−8gr

Step 6: Divide both sides by 4g-5r.

f(4g−5r)

4g−5r

−8gr

4g−5r

−8gr

4g−5r

Answer:

f=−8gr4g−5r

Use the properties of exponents to simplify the expression: 2532

Vlad1618 [11]

Question

Use the properties of exponents to simplify the expression: $25^{\frac{3}{2}}$

Answer:

$25^{\frac{3}{2}} = 125$ \

Step-by-step explanation:

Given

$25^{\frac{3}{2}}$

Required

Simplify

$25^{\frac{3}{2}}$

Apply the following law of indices

$a^{\frac{m}{n}} = (a^m)^{\frac{1}{n}}$

So, the expression becomes

$25^{\frac{3}{2}} = (25^3)^{\frac{1}{2}}$

Express $25^3$ as 15625

$25^{\frac{3}{2}} = (15625)^{\frac{1}{2}}$

In indices: $a^{\frac{1}{2}} = \sqrt a$

So, we have:

$25^{\frac{3}{2}} = \sqrt{15625$

$25^{\frac{3}{2}} = 125$

Solve 3x2 + 4x = 2. (2 points)

guajiro [1.7K]

Answer:

The answer is (-2±√10)/3

Step-by-step explanation:

so if it is 3x^2+4x=2 then

set one side to zero

subtract 2 from both sides

3x^2+4x-2=0

this is not factorable by normal means so use quadratic formula which is if you have the equation in ax^2+bx+c=0 form you can solve for x if you put it into this equation quadratic formula so if you were to input it into this equation you would get

a=3

b=4

c=-2

the solution is: (-2±√10)/3

A=(1+1/2).(1+1/3). ... .(1+1/2020)

Serggg [28]

$A=\left(1+\dfrac{1}{2}\right)\cdot \left(1+\dfrac{1}{3}\right)\cdot\ldots\cdot \left(1+\dfrac{1}{2020}\right)=\dfrac{3}{2}\cdot\dfrac{4}{3}\cdot\ldots\cdot \dfrac{2021}{2020}=\dfrac{\dfrac{2021!}{2}}{2020!}=\\\\=\dfrac{2021}{2}=1010.5$

HELPPPPP!!!!!!!!!!!!!!!!!!!!!!!!!!!!! LCD of 9/14 and 2/21

lions [1.4K]

Least Common Denominator (9/14 and 2/21)

The least common denominator is equal to the least common multiple of the denominators: 14 and 21
The multiples of 14 are: 14, 28, 42, 56, ...
The multiples of 21 are: 21, 42, 63, ...

The least common multiple of 14 and 21, therefore, is 42, and the least common denominator of (9/14 and 2/21) is also 42

Answer:
 $\boxed{42}\end{array}}\qquad\quad\checkmark$
