Answer:
d
Step-by-step explanation:
Hey! First of all, you can express x squared as x^2.
Secondly, the problem! I'm assuming you're asking for the values of x - if you're asking what the equation is, it's a quadratic equation, or a second-degree polynomial. Solving for x, this equation can be factored as (x-4)(x+1)=0. Because either of these two terms being zero will make the whole equation zero, we can have x-4=0, in which case x=4, or x+1=0, in which case x=-1. Therefore, x is either 4 or -1
Answer:
Number of Flowering Plants = 30
Number of vegetable plants = 20
Step-by-step explanation:
Im assuming the question is asking for the number of vegetables and number of flowers.
We need to convert 60% and 40% to decimal. The process is dividing by 100. Hence,
60% = 60/100 = 0.6
and
40% = 40/100 = 0.4
We multiply these with the total number to get number of vegetable and flowering plants.
So,
Number of Flowering Plants = 0.6 * 50 = 30
Number of vegetable plants = 0.4 * 50 = 20
