Equation: 450 = 128 + 150 + n
work:
1st step:
128+150 = 278
2nd step:
450-278 = 172
answer: 172
3rd step (checking) :
450 = 128 + 150 + 172
450 = 278 + 172
450 = 450
(X-3)^2+5=14
Step 1: simplify both sides of the equation
X^2-6x+14=14
Step 2: subtract 14 from both sides
X^2-6x+14-14=14-14
X^2-6x=0
For this equation: a=1, b=-6,c=0
1x^2+-6x+0=0
Step 3: Use quadratic formula with a=1, b=-6, c=0
The answer is x=6 or x=0
First, you must change all of this into improper fractions, like shown below.

Now you must change the sign.

Then we must reciprocalize 2/3.

Now we multiply, to get 2 4/10.
Answer: 90 ft cubed
Step-by-step explanation: Multiply the height, width, and depth. So, 3*5=15. 15*6=90.
Answer:
AAS
