K= 16
25x^2+40x+16x comes to be (5x+4)^2.
Answer:
66
Step-by-step explanation:
11 times 6 = 66
Answer:
54
Step-by-step explanation:
6*5=30
4*6=24
24+30=54
Answer:24 = 24x
Step-by-step explanation:Cross multiply:
2 * 12 = x * 24
Simplifying
2 * 12 = x * 24
Multiply 2 * 12
24 = x * 24
Reorder the terms for easier multiplication:
24 = 24x
Solving
24 = 24x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-24x' to each side of the equation.
24 + -24x = 24x + -24x
Combine like terms: 24x + -24x = 0
24 + -24x = 0
Add '-24' to each side of the equation.
24 + -24 + -24x = 0 + -24
Combine like terms: 24 + -24 = 0
0 + -24x = 0 + -24
-24x = 0 + -24
Combine like terms: 0 + -24 = -24
-24x = -24
Divide each side by '-24'.
x = 1
Simplifying
x = 1
Given:
The point is B(2,5) and its image is B'(1,2.5).
To find:
The scale factor.
Solution:
If a figure is dilated by the scale factor k and (0,0) is the center of then the scale factor is defined as
x-coordinate of point B' is 1 and the x-coordinate of point B is 2. So, the scale factor is
Therefore, the scale factor is 
and the correct option is D.
