Answer:
Step-by-step explanation:
B=0.30m+45
2. B=0.30(210)+45
B=63+45
B=108
The midpoint is kinda the average of the two points,
( (-9 + 7)/2, (-4 + 8)/2 ) = (-1, 2)
Third choice.
Answer:
Stretch
Step-by-step explanation:
- Translation: A translation moves a shape up, down or from side to side but it does not change its size.
- Reflection: A reflection is a transformation which all the points of an object reflect or flip on a line called the axis of reflection or line of reflection. This transformation does not change its size.
- Rotation: A rotation is a transformation that turns a figure about a fixed point called the center of rotation. This transformation does not change figure's size.
- Stretch: A stretch is a transfoormation which stretch the figure (by multiplying by C>1). This transformation changes the size of the figure.
- Isometry: An isometry is a type of transformation that preserves the length of a figure's sides.
Thus, a stretch is not an isometry

Step-by-step explanation:
<u>Linear</u> expression is usually an expression of 1st degree.
A. The product of a number and seven 
Correct, linear
B. The sum of three consecutive numbers.
Let the smallest number be n, the next number is n + 1 and the last number is n + 2. Then their sum is
Correct, linear
C. The square of a number times three.
Let the number be n, then its square is 
and the square of a number times three is
Correct, nonlinear
D. Twice the sum of a number and 8.
If the number is n, then the sum of the number anf 8 is n + 8. Twice the sum is
Incorrect, linear
E. The cube of a number divided by two.
If the number is n, then its cube is 
The cube of the number divided by 3 is
Correct, nonlinear
Answer:
100 units
Step-by-step explanation:
Lengths of diagonals:
PR = 14
QS = 48
Since all 4 sides are equal in length, it's a rhombus
Length of each side:
sqrt[(14/2)² + (48/2)²]
sqrt(625)
25
Perimeter = 4 × 25
= 100
