Answer:
Step-by-step explanation:
our expression is
we are asked to simplify the expression
in order to that we first bring the like terms together
like terms are those having the same variable or same combination of variables with exactly same degrees
Hence it would be like
now we simplify the like terms
Hence
Answer: ((5 / 8) - ((3 / 4) (8 - (1 / 3)))) + 1
-4.125
Step-by-step explanation:
The quadratic formula is -b plus minus the square root of b^2-4ac all over 2a.
Here, a=1, b=13, and c=30.
The only option that fills in the values correctly is D
Answer:
the quickest way would be to "complete the square"
on x^2 + 5x - 7
you will end up with (x+2.5)² = 13.25
or
y = (x+2.5)²-13.25
the vertex
VERTEX: (-2.5,-13.25)
Solution/X-Intercepts: -6.14 AND 1.14
Step-by-step explanation:
<span>4 ⋅ 6 + 5 ⋅ 7 + 6 ⋅ 8 + ... + 4n( 4n + 2) = 4(4n+1)(8n+7)/6
is false because it isn't even true when n=1.
4 ⋅ 6 = 4(4*1+1)(8*1+7)/6
24 = 4(5)(15)/6
24 = 50
Also 4n(4n+2) is not even the correct formula
for the nth term. The correct nth term formula
of 4 ⋅ 6 + 5 ⋅ 7 + 6 ⋅ 8 + ...
is (n+3)(n+5). So it's wrong all the way around.</span>
