The answer is 1/256
Hope this helps!!
In order to see how many real roots it has you have to see what the Δ is
So if Δ>0 then there are 2 real roots
If Δ=0 there is 1 real root
If Δ<0 no real root
And we know that:
Δ=b^2-4ac
So in the equation: Δ=b^2+4 and b^2 is always a number greater than or equal to 0 so when you add 4 to it, it is always greater than 0
So it has 2 real roots
I believe the answer is B , One yard equals three feet .
10-4 is equivelnt to 4-10
Answer:
The answer to your question is z = 87 cm
Step-by-step explanation:
Data
Surface area of the rectangular prism = 8,462 cm²
Find z
Process
1.- Write and equation that help to solve the problem
Surface area = 2(13z) + 2(13)(31) + 2(31z)
-Simplify
8462 = 26z + 806 + 62z
8462 - 806 = 26z + 62z
7656 = 88z
z = 7656/88
-Result
z = 87 cm
