I need to know Simplify 2a + 8(b + a) is

1 answer:

4 0

HELLO !

Okay so what you do is eliminate the parenthesis in the equation because it really helps

So you would multiply 8 and b
Also multiple 8 and a

You would get 8b and 8a

Your equation would look like ...

2a + 8b + 8a = ...

Now you add the alike things in the equation 

8a and 2a are the alike things.

Now you would have ...

10a + 8b = ?

Answer:

Final answer is $x^2$ .

Step-by-step explanation:

Given expression is $x^{\left(\frac{4}{3}\right)}\cdot x^{\left(\frac{2}{3}\right)}$

Now we need to find about what is product of both factors.

We see that both factors are in exponent form having equal base "x".

So we can apply formula: $x^m\cdot x^n=x^{\left(m+n\right)}$

$x^{\left(\frac{4}{3}\right)}\cdot x^{\left(\frac{2}{3}\right)}$

$=x^{\left(\frac{4}{3}+\frac{2}{3}\right)}$

$=x^{\left(\frac{4+2}{3}\right)}$

$=x^{\left(\frac{6}{3}\right)}$

$=x^2$

Hence final answer is $x^2$ .

Answer:

Option C, 262 cm^3

Step-by-step explanation:

Step 1: Substitute 5 for radius and 10 for height

V = 1/3 * pi * r^2 * h

V = 1/3 * pi * (5)^2 * (10)

V = 1/3 * pi * 25 * 10

V = 250pi/3

V = 261.79

Write a number in which the value of the 3 is ten times greater than the value of the 3 in 135, 864

Aleonysh [2.5K]

Answer:

345,456

Step-by-step explanation:

The value of 3 in 135,864 is 30,000.

We want to write a number that is ten times 30,000.

We could write any other number in which the value of 3 is 300,000.

There are infinitely many numbers that we can write.

Some examples are:

345,456

1,315,445

5,354,456

and so on and so forth.

Damm [24]

Answer: Elaine=13 years old Tyler=21 years old

Step-by-step explanation:

Let x = Elaine's age, so her brother Tyler's age = x+8

Elaine+Tyler=34

x+(x+8)=34

2x+8=34

2x=26

x=13

Elaine=13 years old

Tyler=21 years old
