Answer:
Yes
Step-by-step explanation:
There are two cases: Case 1: x is even, so x can be modelled as a generic number 2n, where n is a positive integer. Clearly this product is divisible by two. ... Hence, it is safe to generalise that the term x²-x is divisible by 2 for any positive integer x.
Answer:
1900
Step-by-step explanation:
let a = total seats
the number of students that filled the theatre can be represented with this equation
0.45 x a = 855
divide both sides by 0.45
a = 855/0.45 = 1900

Step-by-step explanation:
Expand the brackets. 7 ( 5 + g ) 11 ( 3s – 4 ) 4 ( 4 – x ) 8 ( 6 + 4w )
We will expand each of the bracket using distributive property
For the expression 7(5+g)
7(5)+7g
= 35+7g
For the expression 11(3s-4)
= 11(3s)-11(4)
= 33s-44
For the expression 4(4-x)
= 4(4)-4x
= 16-4x
For the expression 8(6+4w)
= 8(6)+8(4w)
= 48+32w
