2*5=10 (the measure of one long side is 10)
3*4=12 (the measure of one wide side is 12)
A box has four sides to the perimeter of the flat wrapping paper must consist of four edges. Because we know that one edge is 10 inches long and another side is 12 inches wide we assume that the corresponding sides are equal.
So now we know that we have two sides that are 10 inches and 2 sides that are 12 inches.
10+10+12+12= 44 inches
Answer:
see below
Step-by-step explanation:
given:
radius of a circle = 3cm
find:
1. diameter
2. radius
3. r²
1) diameter = twice the radius = 2 r = 2 (3) = 6 cm
2) radius = 3 cm
3) r² = 3² = 9 cm
In the algebraic expression a constant is a fixed value, and in this case it is 4. If the question was asking for the coefficient, then the answer would’ve been 7 due to to variable being multiplied.
Since we have a negative on the outside of the parenthesis, we can just say that this is -1. So now we have -1(-x + 1). when multiply a negative by a negative it cancels out into a positive. and multiplying a negative with a positive will give you a negative. So now we have x - 1.
