Answer:
18
Step-by-step explanation:
20/2 + 8
Divide the numerator and denominator by 2
20 / 2
2 / 2
Divide the numbers
10
2 / 2
=
10 / 1
Any expression divided by 1 remains the same
10 + 8 = 18
Answer: False
=============================================
Explanation:
I'll use x in place of p.
The original equation 10x^2-5x = -8 becomes 10x^2-5x+8 = 0 after moving everything to one side.
Compare this to ax^2+bx+c = 0
We have
Plug those three values into the discriminant formula below
d = b^2 - 4ac
d = (-5)^2 - 4(10)(8)
d = 25 - 40*8
d = 25 - 320
d = -295
The discriminant is negative, which means we have no real solutions. If your teacher has covered complex or imaginary numbers, then you would say that the quadratic has 2 complex roots. If your teacher hasn't covered this topic yet, then you'd simply say "no real solutions".
Either way, this quadratic doesn't have exactly one solution. That only occurs when d = 0. Therefore, the original statement is false.
Let h,l, and w represent the height, length, and width of the building respectively
Then
The new value of h = 50m, but l remains the same.
That is l = 10m
Therefore
Hence, the width is 2.5m
6 ft for each side, bc area is side times side, which 6x6=36
Answer:
I think the answer is undefined because the question above is an expression of f of x not a statement of variation which should have a constant of proportionality
