U² - 16 u + 64 = ( u - 8 )²
because: A² - 2 A B + B² = ( A - B )²
Answer: 64
Answer:
To get an expression relating to x you need to have x alone on one side of your equation. ie x =
Try this:
rx - st = r
remove st from the rx side
rx = r + st
now divide by r
x = (r + st)/r
You now have your expression relating to x
Answer:
It's 4
Step-by-step explanation:
It asks how many 3/8 cups are in 1 1/2 cups. So, we divide.
1 1/2 ÷ 3/8. We have to change the 1 1/2 into a improper fraction. 1 1/2 = 3/2. 3/2 ÷ 3/8 = 3/2 ÷ 8/3 = 24/6. Simplify, and you get 4. :)
Answer:
Step-by-step explanation:
Since the second equation is fully simplified and we know what x equals, we plug the entire equation of x in for x in the top equation:
Now solve for y.
Now plug y back into the bottom equation and solve for x.
Answer:
Step-by-step explanation:
Given
Initial Temperature = -10
Increment = 5
Required
Solving (a): Write an Equation
The equation is to add the initial temperature and the increment
i.e
Equation = Initial Temperature + Increment
Solving (b): Solve the equation
Substitute values for initial temperature and the increment
Result = -10 + 5
Result = -5
Solving (c):
It's a negative answer because the increment in temperature is not greater than the initial temperature
