Step-by-step explanation:

Where have all the good men gone and where are all the Gods?

Where's the street wise Hercules to fight the rising odds?

Isn't there a white knight upon a fiery steed?

Late at night I toss and I turn and I dream of what I need

I need a hero

I'm holding out for a hero 'til the end of the night

He's gotta be strong and he's gotta be fast

And he's gotta be fresh from the fight

I need a hero

I'm holding out for a hero 'til the morning light

He's gotta be sure and it's gotta be soon

And he's gotta be larger than life, larger than life

Somewhere after midnight in my wildest fantasy

Somewhere just beyond my reach there's someone reaching back for me

Racing on the thunder and rising with the heat

It's gonna take a Superman to sweep me off my feet

I need a hero

I'm holding out for a hero 'til the end of the night

He's gotta be strong and he's gotta be fast

And he's gotta be fresh from the fight

I need a hero

I'm holding out for a hero 'til the morning light

He's gotta be sure and it's gotta be soon

And he's gotta be larger than life

I need a hero

I'm holding out for a hero 'til the end of the night

Up where the mountains meet the heavens above

Out where the lightning splits the sea

I could swear that there's someone somewhere watching me

Through the wind and the chill and the rain

And the storm and the flood

I can feel his approach like a fire in my blood

I need a hero

I'm holding out for a hero 'til the end of the night

He's gotta be strong and he's gotta be fast

And he's gotta be fresh from the fight

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
