Whatt? the answer is 7z+84
there is not a single X in the equation i really dont know where you got the X
Answer:
Step-by-step explanation:
Expand brackets.
This is in quadratic form.
Since this is for equal roots:
Plug k as 0 to check.
False.
So that means k must equal 6.
Since the only two corresponding side you have are 10 units and 4 units, you can divide these two numbers to get the scale factor.
10÷4=2.5
next you find the sides corresponding to X Y and Z and if it is on the bigger figure you divide, if it is on the smaller side you multiply
X corresponds with 5 (so ×2.5)
Y corresponds with 8 (÷2.5)
Z corresponds with 10 (÷2.5)
final answer is X=12.5 Y=3.2 Z=4
I try to explain the question and give the answer, I hope this helps!
Answer:3/0=undefined
Step-by-step explanation:(5/6) and (5,9)
Slope: 9-6 = 3
5-5 = 0
4x^2-25= (2x)^2-5^2=(2x-5)(2x+5)
Used: a^2-b^2=(a+b)(a-b)
