Answer: 25%
Step-by-step explanation: 100-75=25
<em><u>The pair of like terms are:</u></em>

<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>

We have to find the pairs that are like terms in the given expression
Like terms means that, terms that have same varibale but different ( or same ) coefficients
Here in the given expression "x" and "y" are the two variables present
Arrange the like terms

So here the first two terms has same varibale "y" but different coefficients. So they form a pair of like terms
"x" is present only once . There is no other term with variable "x"
6 and -2 are constants
So the pair of like terms are:

Answer:
The time the object takes to fall on the ground from 224 feet is 3.74 s.
Step-by-step explanation:
In this case we have a known quantity, the distance of the fall that is 224 feet and a equation that represents the motion of this fall that is d = 16t^2. We wish to find the time it'll take this object to fall, so we can solve this equation for t. It goes as follows:
d = 16t^2
d/16 = t^2
t^2 = d/16
t = \sqrt(d/16)
t = [\sqrt(d)]/4 = [\sqrt(224)]/4 = 14.97/4 = 3.74 s
where \sqrt is the square root of the number.
