Answer:
√7x−49√x
Explanation:
First of all, expand by multiplying √7x⋅√x and √7x⋅7√7respectively:
√7x(√x−7√7)=√7x⋅√x−√7x⋅7√7
... you can express √7x as √7⋅√x...
=√7⋅√x⋅√x−√7⋅√x⋅7⋅√7
=√7⋅(√x)2−(√7)2⋅√x⋅7
... the operations squaring and taking the square root "eliminate each other"...
=√7⋅x−7⋅√x⋅7
=√7x−49√x

Answer:
b. 75
Step-by-step explanation:
a(n) = a1 + d(n-1)
a(n) = 8.5 + 3.5(n - 1)
a(20) = 8.5 + 3.5(20 - 1)
a(20) = 8.5 + 3.5(19)
a(20) = 8.5 + 66.5
a(20) = 75
Answer:
The correct option is;
a. F is the midpoint of because line bisects
Step-by-step explanation:
Here, since we have that the triangle is reflected across EG therefore the location of the point F which is along EG bisects the line as the dimensions of the line from A to F must be equal to the dimension of the line that extends from A' to F
Therefore the point F is the midpoint of because line bisects .
