x + 8
the sum of the internal angles of an 8 sided shape is; number of sides (8) subtract 2 (8-2=6) multiply by 180 (6x180=1080)
sum interior angles = (number of sides - 2) × 180°= (8 - 2) × 180°= 1080°The sum of the interior angles of an octagon is 1080°In a regular octagon, divide by 8 for each angle = 135°.
As an algebraic expression it is simply: 8+q
The sum of a number x and 84
The sum of p and q means (p+q). The difference of p and q means (p-q).
Watch carefully:Q + 8 = 9Subtract 8 from each side of this algebraic linear equation:Q = 1 .
three-fourths of the sum of q and 5
q - p
The expression is simply: 9+q
We can not provide a specific value as an answer to this question as both p and q are variables and their value is unspecified.However we can write this as:-8(p + q).We can multiply out the bracket to get:-8p + -8q.This is as far as we can answer this question unless the values of p and q are known.-8(p + q) = -8p + -8q
It is: 4*(q+p)
the sum of q plus 5!
The sum of 8 and 2 is 10
