Answer:
is equivalent to 24m-28
Step-by-step explanation:
The distributive property enables us get rid of parentheses by multiplying the term outside by each of the term inside; a bit like algebraic expansion
It states that:
Therefore
Thus 24m-28 is the equivalent expression
Answer:
1st option
Step-by-step explanation:
the area of the shaded portion is calculated as
area of sector - area of white Δ
area of sector = area of circle × fraction of circle
= πr² × ( r is the radius )
= π × 8² ×
= 64π ×
= 16π in²
area of Δ = bh ( b is the base and h the perpendicular height )
here b = h = 8
area of Δ = × 8 × 8 =
× 64 = 32 in²
then
area of shaded portion = (16π - 32 ) in²
