Answer:
yes; 1.25
Step-by-step explanation:
The length to width ratios of the rectangles are ...
A: 12/8 = 1.5
B: 15/10 = 1.5
C: 30/15 = 2.0
__
Rectangles A and B have the same aspect ratio, so are similar. Rectangle B is a scaled copy of A with a scale factor of 10/8 = 1.25.
I need a question to answer first.
Subtract 20n from both sides of the equation.
n^2+100-20n=0
factor using the perfect square rule.
(n-10)^2=0
set the n-10 equal to 0.
n-10=0
add 10 to both sides of the equation.
n=0
Answer:
4x -2 = 3 and 4x + -2 = 3
Step-by-step explanation:
-2 + 4x = 3 ---- 4x -2 = 3 ------------ 4x + -2 = 3
+2 +2 - 2 +2
------------------ ----------------
4x = 5 4x = 5
---- ---- ----- -----
4 4 4 4
x = 1.25 or 1 1/4 x = 1.25 or 1 1/4
