Answer:
No, the answer is 120 plants per square foot
Step-by-step explanation:
What I did was first figure up the area of the triangle. You want to do this because the area will tell you how many square feet are in the garden. In order to find this, you need to use this formula: 1/2 b·h
Plug in the numbers like this: 1/2·15·8
15 is the base of the triangle, while 8 is the height of the triangle. Now solve your equation.
15·8=120
1/2·120=60
Area = 60
Now you know that the area is 60ft². So there are 60 square feet in the whole garden. But, we're not done yet. Jessica wants to put 2 plants in every 1 square foot. So now, we need to multiply 60 by 2 in order to get 2 plants in every 1 square foot.
60·2=120
Jessica can put 120 plants in the garden if she is wanting 2 plants per square foot.
I hope this makes sense and is easy to understand. Please let me know if you need any more help or clarification. I'm always happy to help! Have a great day and good luck!!

Answer:
The only correct answer is:
All positive numbers have two square roots
Step-by-step explanation:
This is true because in any situation all positive numbers have two square roots. For example, the square root of 25 is +/- 5 which means that 5 is a square root (because 5x5=25) and -5 is a square root (because -5x-5=25).
The others such as 18 = 9, 149 = 7, and 25 = 5 are all false statements.
18 chocolate cakes were made. 40(3)= 120 cakes in total. 15%=.15 .15(120)= 18
