<em><u>That isn't true</u></em>
<em><u>9+10=19</u></em>
<em><u>Good Lucks</u></em>
We can take out 7 because all of the terms include it:
7(-x^2+2x-3)
Take out negative 1:
-7(x^2-2x+3)
We cannot factor any further so the final answer is:
-7(x^2-2x+3)
Step
Divide by to find the number of cut pieces
so
therefore
the answer is
9 * 12 = 108
the base is 9 and the height is 12
now the formula for the area of a triangle is 1/2 *(b)*(h)
multiply 9 * 3 = 27
multiply 12 * 3 = 36
multiply base = 27 * height = 36
27 * 36 = 972
now divide that by 2
486 sq cm.
Answer:
Since it takes 7 people 28 minutes to paint 7 walls, it must take 1 person 28 minutes to paint each wall. Therefore, 14 people must also take 28 minutes to paint 14 walls, as each person still paints 1 wall individually.
