Answer:

  3 and 7

Step-by-step explanation:

You know from your multiplication tables that ...

  21 = 1×21 = 3×7

There are no other factorizations of 21 using integers. You may notice that the sums of these factors are ...

  1+21 = 22

  3+7 = 10 . . . . . . this is the pair of numbers you are looking for

The two numbers are 3 and 7.

Which of the following describes the zeroes of the graph of f(x) = 3x6 + 30x5 + 75x4?
andre [41]

we have

f(x)=3x^{6}+30x^{5}+75x^{4}    

<u>Find the zeroes of the function</u>

f(x)=3x^{6}+30x^{5}+75x^{4}  

f(x)=3x^{4}(x^{2}+10x+25)

 f(x)=3x^{4}(x+5)^{2}  

The zeroes of the function are

x=-5 -------> with multiplicity 2

x=0 -------> with multiplicity 4

therefore      

<u>the answer is the option </u>

–5 with multiplicity 2 and 0 with multiplicity 4    

see the attached figure

Compare the following fraction <br>4/3 and 5/2<br>-3/2. -4/5​
zavuch27 [327]

Answer:

Step-by-step explanation:

to compare them, we need to convert them into like fractions

4/3 and 5/2

lcm of 3 and 2 is 6

4/3 × 2/2 = 8/6

5/2 × 3/3 = 15/6

15/6 is greater than 8/6

<em><u>so 5/2 is greater than 4/3</u></em>

similarly,

-3/2 and -4/5

we need to convert them into like fractions

lcm of 2 and 5 is 10

-3/2 × 5/5 = -15/10

-4/5 × 2/2 = -8/10

-8/10 is greater than -15/10

<u><em>so -4/5 is greater than -3/2</em></u>

Hope this helps
