Mathematics
1 answer:
ololo11 [35]4 years ago
8 0

Step-by-step:

For example,

(x+4)(x-4)(x-3)

group the first two and do foil like normal ignoring the "(x-3)"

You should end up with the answer x^2-16

Now multiply (x^2-16) with (x-3)

that answer should be x^3-3x^2-16x+48

The ratio of Dina’s bathing suits to Yana’s bathing suits was 4:1. if Dina has 24 more bathing suits than Yana, how many bathing
lina2011 [118]

Answer:  Yana has 8 bathing suits.

Step-by-step explanation:  Given that the ratio of Dina’s bathing suits to Yana’s bathing suits was 4 : 1 and Dina has 24 more bathing suits than Yana.

We are to find the number of bathing suits that Yana has.

Let 4x and x represents the number of bathing suits that Dina and Yana have respectively.

Then, according to the given information, we have

4x-x=24\\\\\Rightarrow 3x=24\\\\\Rightarrow x=\dfrac{24}{3}\\\\\Rightarrow x=8.

Therefore, the number of bathing suits that Yana has is given by

x=8.

Thus, Yana has 8 bathing suits.

How many different 2-digit numbers are there with the following property:the tenth digit is greater than the units digit?
Serggg [28]

Answer:

45

Step-by-step explanation:

Simply start by listing out the numbers from smallest to largest.

We start out with the smallest number following this information being the number 10. The next are 21 and 20. The next are 32, 31, and 30. We can start to see a pattern. If the ten's digit is n, then there are n numbers within that ten-group that have a greater 10's digit than unit's digit. The largest ten-group (90 to 98) has 9 integers following the rules established. Thus, the number of 2-digit integers that have ten's digits greater than units digit is 1+2+3+...+9=45
