hoa [83]

Answer:

$r = \dfrac{23}{20} p$

Step-by-step explanation:

Number of points scored by River = $r$

Number of points scored by Paul = $p$

River has scored 15% more points that Paul.

To find:

Equation to represent the given condition.

Solution:

As per the given question statement, Number of points scored by River is 15% more than that of Paul's.

15% of points scored by Paul = 15% of $p$ = $\frac{15}{100}p$

15% more means total points scored by Paul plus 15% of points scored by Paul.

Therefore, we can write the following:

$r = p + 15\%\ of\ p\\\Rightarrow r = p + \dfrac{15}{100} p\\\Rightarrow r = \dfrac{115}{100} p\\\Rightarrow r = \dfrac{23}{20} p$

Which choice shows the expression 4x2 + 13x + 9 in factored form?

Aleonysh [2.5K]

Answer:

4x²+13x+9

iwill give you good method to simplify this

firstable take the 4 from x² and multiply it by 9

x²+13x+36

we find this equation

so the values is 4 and 9 because 4+9=13

4×9=36

(x+ )×(x+ )

first we take 9 and devide it by 4

9/4 the four for the x and the nine is number

so its will be

(4x+9)×(x+ )

same thing with 4 devide by 4 so the value is 1

so its will be like this

(4x+9)×(x+1) and this is the answer hopefully you understand my explain with my English
