. Write the following expression in factored form using the greatest common factor. 50a3 + 10a2

1 answer:

3 0

The factors of 50a³ are 1, 2, 5, 10, 25, 50,
   and their products with a, a² and a³ .

The factors of 10a² are 1, 2, 5, 10,
    and their products with 'a' and a² .

Their common factors are 1, 2, 5, 10,
   and their products with 'a' and a².

Their greatest common factor is 10a² .

(Another way to spot it, easily, is to remember this helpful factoid:

   If the smaller number is a factor of the larger number,
   then the smaller number is their greatest common factor.

Using the greatest common factor, then . . .

   50a³ + 10a² =   10a²(5a + 1) .

Can someone please explain how to solve it ??

if we look on one side, we already have one measurement. 4 cm. ok, that's the measurement on that side. look to the left now. that other side is also the same length, so we take that number and multiply it be 2 to get

$4 \times 2$

Wait! we're not done yet. look at the top. do you see the 3? well that's the width for the top of the rectangle. the bottom must be the same to right? so we get

$3 \times 2$

add both equations and you get

$(4 \times 2) + (3 \times 2)$

The answer is 14cm! Don't forget to label. ;)

Convert the decimal expansion 0.1777 into a rational number

Helen [10]

Answer:

The rational form of the given number 0.1777 = $\frac{1777}{10,000}$

Step-by-step explanation:

The rational number is expressed as a number on the form of $(\frac{p}{q} ) , q \neq 0$

Now,here the given number in decimal form = 0.1777

To remove the decimal, firstly count the number of digits AFTER DECIMAL.

Here, number of digits after decimal = 4

SO, the decimal can be removed and replaced by 1 , by dividing with 1,0000.

$\implies 0.1777 = \frac{01,777} {10,000} = \frac{1777}{10,000}$

Hence, the rational form of the given number 0.1777 = $\frac{1777}{10,000}$

Find three consecutive even numbers whose sum is 1884.

Scilla [17]

Answer:

smallest number=626

middle number=628

larger number=630

Step-by-step explanation:

To find the numbers, let's use n as the variable. Since we know that the numbers are consecutive even numbers, we know that they increase by 2. For example, we could have 2+4+6=12.

Knowing that the consecutive numbers increase by two's, we can use this.

smallest number: n

middle number: n+2

larger number: n+4

All we have to do is add these together and set it equal to 1884.

n+(n+2)+(n+4)=1884 [combine like terms]

3n+6=1884 [subtract both sides by 6]

3n=1878 [divide both sides by 3]

n=626

Now that we know n=626, we also know that the other numbers are 626, 628, 630 respectively.
