Hello there!
Here is the answer worked out for you!
12x[-1+sqrt(5)]
-12x+12xsqrt(5)
Remember that you can only add like terms so you can't add -12x to 12xsqrt(5). The radical makes it an unlike term.
I hope this helped and best wishes!
Answer:
17260
Step-by-step explanation:
multiply 14400 by 20%
After that add 14400 and 2880together
and you got the answer
The green square is 15 ft wide by 15 ft tall.
The area of one green square is 15 x 15 = 225 square feet.
There are 4 sides plus the base : 225 x 5 = 1125 square feet for the green part.
One triangle has a base 15 feet wide and a height of 9 feet.
The area for one triangle is 1/2 x 15 x 9 = 67.5 square feet.
There are 4 triangles: 67.5 x 4 = 270 square feet.
Total: 1125 + 270 = 1,395 square feet.
Answer:
Alex is right so the problem is solved
Polygons, Number of sides, Measure is angles, and angle sums
