Answer:
314
Step-by-step explanation:
Answer: a-b+c+d =4
Step-by-step explanation:
The given system of equation is
from this we have the following matrices
the given matrix A =
On comparing Matrix 
with Matrix A
we have the following values
a=2 ,b=4,c=8,d=-2
Thus a-b+c+d =2-4+8+(-2)=4
Answer:
A. The perimeter of the original figure is multiplied by 3 ,and the area is multiplied by 9.
(9=3²)
it is a rule in the dilation course:
<span>See examples for the method to solving literal equations for a given variable: Solve A = bh for b. Since h is multiplied times b, you must divide both sides by h in order to isolate b. Since (c+d) is divided by 2, you must first multiply both sides of the equation by 2</span>
The formula to find the volume of a cylinder is v= hㅠr*2, so you can sub the measurements into the formula.
V = (6)ㅠ(2)*2
V = 6ㅠ4
V= 75.4 (approx)
