Answer:
Step-by-step explanation:
90 × 3=270 dollars
6×3= 18 lawns
Answer: x=3
Step-by-step explanation:
To find the zeros, you want to first factor the expression.
x³+x²-36
(x-3)(x²+4x+12)
Now that we have found the factors, we set each to 0.
x-3=0
x=3
Since x²+4x+12 cannot be factored, we can forget about this part.
Therefore, the zeros are x=3. You can check this by plugging the expression into a graphing calculator to see the zeros.
No, it never can be a right triangle.
First, all the angles of an equilateral triangle is 60 degrees because all angles are the same and all the angles add up to 180:
180/3 = 60.
So if it is a right angle it needs one angle 90 degrees which an equilateral triangle can't have,
Answer:
Number 1 is a right triangle
Number 2 is a right triangle
Number 3 is NOT a right triangle
Number 4 is NOT a right triangle

Hope this helps :)
11,340 I believe. 5% of 8400 is 420. 420*7=2940 2940+8400=11340
