The white Christmas tree is 7.55m
Green Christmas tree is twice as tall as white Christmas tree: 7.55 * 2 = 15.1m
High golden Christmas tree: 15.1m - 0.454m = 14.646m
The total height of 3 Christmas trees is: 7.55m + 15.1m + 14.646m = 37.296m
Choose: A 37.296m
Answer:
Step-by-step explanation:
First, we need to set up the equation
To solve this, we have two options: factoring or using the quadratic formula. In this case, factoring will work, so we can use that
To factor, we need to find two numbers that add together to give you 3 and multiply to give you -28
In this case, these two numbers would nee to be -4 and 7
This means that our factored equation would be:
Now all we need to do is input the values of x that will give you 0. This means that the two solutions are
A) 3/7 and B) 25%. Give me a like if I helped please :)
