Answer:
±10i
Step-by-step explanation:
sqrt( -100)
sqrt( 100*-1 )
We know sqrt(ab) = sqrt(a) sqrt(b)
sqrt(100)sqrt(-1)
We know that sqrt(-1) = i
±10i
Given: 12x +20
factor out a two: 2(6x +10)
factor out a four: 4(3x+5)
factor out 3/4: 3/4(9x +15)
factor out 1/2: 1/2(6x +10)
Hint: think of Multiples of 12 and 20
Hope this helps!
Answer:
F=24
Step-by-step explanation:
Multiply all terms by the same value to eliminate fraction denominators
4 x f/4 = 4 x 6
So f=24
Area is length • height and a square is equal in all sides, so 81/2 equals 9
Each side is 9 and the perimeter sides add together and a square has four sides
9+9+9+9 or 9 • 4 equals 36
36 square inches is the answer
He wants to earn 112 per day. He earns 40 per day. He has 112-40=72 more to earn per day. To find how many shoes he must sell, 4.5p = 72. He must sell 16 shoes.
