Answer:
9<sqrt(97)<10

Step-by-step explanation:
Perfect squares:
1
4
9
16
25
36
49
64
81
100
121
144
169
....so on

97 is between 81 and 100
So square root of 97 is between sqrt(81)=9 and sqrt(100)=10.

9<sqrt(97)<10

Solve for n. n+ 1 = 4(n-8) On=1 O n= 8 on = 11 On = 16

Lesechka [4]

Answer:

n = 11

Step-by-step explanation:

n+ 1 = 4(n-8)

<=> n + 1 = 4n - 4×8

<=> 4n - n = 1 + 4×8

<=> 3n = 33

<=> n = 11

Answer:

4 miles

Step-by-step explanation:

Let

x ----> the time to returned back biking in hours

d ---> the distance in miles

s ---> speed in miles per hour

Remember that

The speed or rate is equal to divide the distance by the time

$s=\frac{d}{t}$

The distance is equal to multiply the speed by the time

$d=st$

we know that

$18\ min=\frac{18}{60}\ hours$

The distance to his friend's house and the distance of return is the same

$10x=4(x+\frac{18}{60})$

solve for x

$10x=4x+\frac{18}{15}$

subtract 4x both sides

$10x-4x=\frac{18}{15}$

$6x=\frac{18}{15}$

$x=\frac{1}{5}\ hours$

The total distance of the round trip is

$y=10x+4x+\frac{18}{15}$

substitute the value of x

$y=10(\frac{1}{5})+4(\frac{1}{5})+\frac{18}{15}$

$y=2+2=4\ miles$

Solnce55 [7]

A.) Simplifying the equation would lead you to 15x^2-3x+9

b.) You know your answer is correct because you're adding the two polynomials together. 9x^2+6x^2 is 1tx^2. Now you have 2x-5x and since the negative is bigger, you get -3x. Then 5+4 is 9. You have no like terms therefore your answer is 15x^2-3x+9
