3w. you find common factor for each. For 12 and 15 it is 3. For w and wz it is w. Combine them together you get the answer.
The answer is 41
Step-by-step explanation:
To solve this we must use the formula a^2+b^2=c^2. if we substitute in the values we get 9^2+40^2=c^2. The first variable is 81, then the b variable is 1600. The hypotenuse is the c value. 81+1600 is 1681, now we must find the square root of 1681. The answer is 41. Tell me if I'm wrong :)
Using the Pythagoras theorem,
21²=4²+height²
441=16+height²
425=height²
height=√425=20.6
The ladder reaches a height of 20.6 ft on the building.
Your zeroes are x=-2, x=sqrt 3 i, and x=-sqrt3 i
