Answer:
m∠GKH = m∠JKI Subtraction Property
Step-by-step explanation:
Given:
Line GI intersects line JH at point K. The proof of ∠GKH ≅ ∠JKI is shown.
To complete the 5th step in the proof.
Solution:
In order to prove ∠GKH ≅ ∠JKI , we need to first show that m∠GKH = m∠JKI .
We can use properties of equality to prove it.
4th Step is as follows :
Using subtraction property:
Subtracting both sides by m∠HKI
Thus, we have the 5th step as:
Answer:
(x,y)= (-1,-4)
Step-by-step explanation:
y=4x
put this value of y in 3x-y=1
3x-4x=1
-x=1
x= -1
y=4(-1)
y= -4
So (x,y) ordered pair is (-1,-4)
Answer:
see below
Step-by-step explanation:
We can write the length as w + 8 and since area is length * width our answer is w * (w + 8) = w² + 8w.
Since 9 is a factor of an unknown number, that means that that number has to be a multiple of 9. If 9 is the factor of something then that something HAS to be a multiple of 9.
Answer:
396
Step-by-step explanation:
Difference of two squares is breaking down numbers into pieces and using the distributive property to solve. The pieces should be in the form (a-b)(c+d).
Write 22 as (20 + 2) and 18 as (20-2).
(20+2)(20-2) = 400 + 40 - 40 - 4 = 400 - 4 = 396
