Answer:
this is an example
Step-by-step explanation:
The expression that is equivalent to √1,120y is: 4√70y.
<h3>What are Equivalent Expressions?</h3>
Expressions are said to be equivalent when the value of one is the same as the value of the other when evaluated or simplified.
Given the expression, √1,120y, we can simplify as shown below:
√(16 × 70 × y)
= 4√70y
Thus, 4√70y is equivalent to √1,120y .

Adding four and subtracting one is the same as adding three. So, to see if a number can be in this pattern, subtract five and check if the result is a multiple of three. If it is, it can be in the pattern.
Fun fact: to check if something is a multiple of three, add all the digits up and see if that is a multiple of three. If you don’t know, repeat the process of adding the digits.
(I'm assuming the first term is 10 b squared)
The first thing you need to know before diving in is to find the factors of 10 and 3.
10 = 1x10, 2x5
3 = 1x3
Next you will have to find a combination that when multiplied the middle term is 17. In this case it is 2x5 and 1x3. We can test it out by setting it up in binomials.
(2b + 3)(5b + 1) = 10b squared + 2b + 15b + 3 = 10b squared + 17b + 3.
The reason why the binomials are additions is because both the middle and end terms are positive.
Hope this helps!
The centre of the circle is the middle of the two endpoints
so centre M is M(1,2) so the two last options aren't valid since those would be M(1,-2) and M(-1,2)
The radius would be half the distance of the two endpoints so
√(1+2)^2+(2-1)^2
√9+1
√10
so the answer is the second one
