Answer:
6
Step-by-step explanation:
Step 1:
3 ( 2x - 5 ) - 4x + 8 = - 1
Step 2:
5x - 15 - 4x + 8 = - 1
Step 3:
x - 15 + 8 = - 1
Step 4:
x - 7 = - 1
Answer:
x = 6

The equation is equivalent to x2/25 + y2/(25/<span>9)</span>= 1, it is an ellipse equation
the center is C(0,0)
a=5; b= 5/3, so a>b it is a horizontal major axis type (the x-axis)
all that you do is to find all characteristics by following all required formula
Answers -
statement B, D, E are correct .
Solution -
As figure B is the scaled copy of figure A, so it is smaller than B and its perimeter is also less than that of A.
On the other hand , as B is the smaller replica of A, so it has same number of edges ,angels and sides. Though the length of the sides are not same, the angels are same. so the perimeters of both figures are different but sum of all the angels are same.
