VERY DIFFICULT!! HELP NEEDED

Answer:

9x ^2 − 25

Explanation:

( a + b ) ( a − b ) = a ^2 − ^b 2

substitute  a  with  3 x  and  b  with 5:

( 3 x + 5 ) ( 3 x − 5 ) = ( 3 x ) 2 −5^ 2 = 9 x ^2 − 25

( 3 x + 5 )( 3 x − 5 ) =  9 x ^2 − 25

Answer:

9x² - 25

Step-by-step explanation:

(a - b)(a + b)= a² - b²

a = 3x   ; b = 5

(3x - 5 )(3x + 5)= (3x)² - 5²

                        = 3²x² - 25

                        = 9x² - 25

Answer: [tex](\sqrt[3]{x} )^8[/tex]

Step-by-step explanation:

Radical expression :

Cube root of any expression 'a' = [tex]\sqrt[3]{a}[/tex]

Radical exponent:

'a' to the power n = [tex]a^n[/tex]

Similarly cube root of x = [tex]\sqrt[3]{x}[/tex]

cube root of x to the power of 8 = [tex](\sqrt[3]{x} )^8[/tex]

Now , the required radical expression with rational exponents for "cube root of x to the power of 8" = [tex](\sqrt[3]{x} )^8[/tex]

Hence, the required expression =[tex](\sqrt[3]{x} )^8[/tex]

Answer: Increasing her speed  by 5km/h, she will take 4.5 hours to complete the journey.

Step-by-step explanation:

Step 1

Speed= Distance  / TIme

Given Speed = 45km/h

and Time = 5 hours

Distance covered = Speed x Time

= 45 km/h x 5 hours

=225 kilometres.

Step 2

Increasing her speed by 5km/h makes the new Speed = 45 +5 = 50 km/h

At the same Distance of 225 km

Therefore she will complete the journey in

Time = Distance/ Speed

=225km/ 50km/h

=4.5 hours

Answer:

Step-by-step explanation:

1:8= 7:?

1*?=7

/1   /1

1*7=7

8*7=56

1:8 = 7:56

Answer:

7:56

Step-by-step explanation:

1:8

we need to turn the one into seven. Turn the ratio 1:8 into the fraction 1/8.

multiply by 7/7 to turn the one into seven and 8 into 56

7/56 can now be turned into ratio 7:56. You could omit the turning of the ratio into the fraction at the beginning, but I find it makes it simpler.

Answer:

1. $161.50

2. $68.04

Step-by-step explanation:

Answer:

5 hamburgers and 3 hot dogs

Step-by-step explanation:

D = number of hot dogs

H = number of hamburgers

D + H = 8    then  D = 8 - H

1.50D + 1.75H = 13.25

substitute for D

1.50(8-H) + 1.75H = 13.25

12-1.50H + 1.75H = 13.25

subtract 12 from each side

-1.50H + 1.75H = 1.25

0.25H = 1.25

divide both sides by 0.25

H = 5

D = 8-5

D = 3
