Answer:
C
Step-by-step explanation:
x²+2x-15 = x²-3x+5x-15 = x(x-3)+5(x-3)=(x+5)(x-3)
or delta:
∆=2²-4*1*(-15)=4+60=64
√∆=8
x1 = (-2+8)/2 = 3
x2=(-2-8)/2=-5
and 4x+20 = 4(x+5)
The same is (x+5), so it is GCF. answer C
Answer:
Step-by-step explanation:
Given: 
.
we need to find the correct form for 
if the equation is solve using undetermined coefficients.
A first order differential equation 
is said to be homogeneous if 
for all t.
Consider homogeneous equation 
Let 
be the solution .
We get 
Since 
, 
.
So, we get solution as 
As constant term and 
are already in the R.H.S of equation
, we can take as

Answer:
All make numbers make that statement true
Step-by-step explanation:
6406358 + 8550780= 14957138
14957138-5598256= 9358882
therefore is you add any number to 5598256 that is greater than 9358882 then the statement will be true. All those numbers given are larger than 9358882
