Answer:
< 4, - 7 >
Step-by-step explanation:
- w - z
= - < - 5, 3 > - < 1, 4 > ← multiply each component in w by - 1
= < 5, - 3 > - < 1, 4 > ← subtract corresponding components
= < 5 - 1, - 3 - 4 >
= < 4, - 7 >

<u>Answer:</u> The wavelength for X-rays with the given frequency is 
<u>Step-by-step explanation:</u>
To calculate the wavelength of light, we use the equation:
where,
= wavelength of the light
c = speed of light = 
= frequency of light = 
Putting the values in above equation, we get:
Hence, the wavelength for X-rays with the given frequency is
Answer:
X=25
Step-by-step explanation:
Remove parentheses
7x - 5x - 40= 10
Merge the similar terms
2x - 40= 10
Constantly move to the right side and change characters
2x = 10 + 40
Addition
2x = 50
Divide both sides of the equation by 2
x = 25
Hey there,
Length = 4x
Width = 3x
Perimeter = 112 inches
4x + 3x + 4x + 3x = 112 inches
14x = 112 inches
x = 112 inches / 14
= 8 inches
Length = 8 inches x 4
= 32 inches
Width = 8 inches x 3
= 24 inches
Hope this helps :))
