Answer:


Step-by-step explanation:

First write it the shorter way. Leave out the middle term. What you have is the difference of squares.

a^2 - b^2 = (a + b)(a - b)

4x^2 - 9

Jason cycled for 3 hours. He cycled 7 1/2 miles each hour for the first two hours and the distance he cycled for the third hour
suter [353]

Answer:

Total distance Jason cycled = 20 miles

Step-by-step explanation:

Distance covered in first 2 hours = 2( 7.5)

                                                         =15

Distance covered in the 3rd hour = 15/3                    

                                                                  = 5

Dividing by 3 because the distance covered in the 3rd hour is 1/4 of the distance covered in first two hours. By dividing by 3 we will get 1/4 of the distance

Total Distance =  Distance covered in first two hours

                             + Distance covered in  the 3rd hour                                                                                                                      

                                                                                                       

                             =15  + 5

Total Distance  = 20

Write an inequality for each of the following:
laila [671]

Answer:

1.\ \ \frac{x}{24}

Step-by-step explanation:

1. let x be the unknown number.

-Given that 24 divided by x is less than x is less than 7 means that 7 is greater than the quotient thereof.

-The in equality is written as:

\frac{x}{24}

2.Let the amount Chris has be y.

-At most is a term of inclusivity implying less than or equal to a specified quantity.

-$5 less than twice y will therefore be represented as:

2y-5\leq 124

3. It is clear that the minimum age to have a drivers license is 16.

-Let x be the age of a driver whose age is unknown.

-It is therefore obvious that all drivers in Ohio are either exactly 16 years or older.

-Our inequality symbol is that of equal to or greater than, thus:

x\geq 16

4. let x be the number of CD's bought and y of DVD's bought.

-CD's are priced at $14 each and DVD's at $16 each, given a budget of $65.

-They can only buy a number of units whose price is less than or exactly $65, thus:

14x+16y\leq 65

What is the value of a^3, if a =7
alekssr [168]
Ok so remember
x^n means x times itself n times
example
x^2=x times x
x^4=x times x times x times x
so

a^3
a=7
a^3=a times itself 3 times therefor
a^3=a times a times a
subsitute 7 for a
7^3=7 times 7 times 7
7^3=343
