Answer:
X1=-4+4i
X2=-4-4i
Step-by-step explanation:
X^2+8x+32=0
Δ=b^2-4ac=8^2-4(32)=-64<0
X1=(-b-i√Δ) /2a=(-8-8i)/2=-4-4i
X2=(-b+i√Δ) /2a=(-8+8i)/2=-4+4i
Answer:

Step-by-step explanation:
We have been given that
and
. We are asked to find the expression that represents length of PS.
We know that
.
Upon substituting our given values in above equation, we will get:




Therefore, the expression
represents length of PS.
Answer:
L*W
Step-by-step explanation:
As we Know tha area of a rectangle is Leght*witdth so in this case will be L*W but lets prove it by calculating the integral:
Area= L*W= 
So as the integral of a constant is the constant multiplied by the integration variable x.
The integral becomes: L*W(x) where W(x) in this case is W= L*W
Good luck!
Answer:
Figure out how their teacher, teaches them and try to mimic that learning style. So the child's learns with one way and not multiple.
Step-by-step explanation:
Answer:
Step-by-step explanation:
-k - ( -8k + 7)
negative sign is outside the parenthesis. so it should be multiplied with -8k and 7
-k - (-8k + 7) = -k - 8k * (-1) + 7*(-1)
= -1k + 8k - 7
Now -k and 8k are like terms. So, combine them.
= 7k - 7
