(25-y) ^2-y^2=25
y=12
x=25-12
x=13
(13,12)
Answer:
x + y : x - y = (5/2+1/2) : (5/2-1/2)
x + y : x - y = 3 : 2
Therefore, x + y : x - y= 3 : 2 is proved.
Step-by-step explanation:
Given
x + y : x - y = 3 : 2
As


Solving to find x and y






solve for y

Divide both sides by 2






so

Thus,
x + y : x - y = (5/2+1/2) : (5/2-1/2)
x + y : x - y = 3 : 2
Therefore, x + y : x - y= 3 : 2 is proved.
Answer:
A. 28.1 cm^2
Step-by-step explanation:
a = bh
a = (7.6)(3.7)
a = 28.12 cm^2
a = 28.1 cm^2
156÷13
13 goes into 15 once
so under the 156 put 13 under 15 left with 2 bring down the 6 to make it 26
13 goes into 26 2 times
so under where you wrote 26 put 26 then 26-26=0
so your answer is 12
The solution to the problem is as follows:
<span>ln(0.5) could be written as ln(2) - ln(2) - ln(2) = a - a - a = -a
