Factorise the following expressions :​

√L -16L + 64

√L-8L-8L+64

(√L-8L)-(8L+64)

L(L-8)-(-8)(L-8)

L(L-8)+8(L-8)

L+8(L-8)

Step-by-step explanation:

HOPE IT HELP U THX TO MY ANSWER AND MARK IT AS BRAINLIST

ii) l² - 16l + 64

= l² - 2.8l + 8²

= (l - 8)²

v) 25m² - 40mn + 16n²

= (5m)² - 2.5.4mn + (4n)²

= (5m - 4n)²

dont know

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
