Answer:
- (x +1)² = 4
- (D) x = -1 ±2
Step-by-step explanation:
Start by getting the x-terms on one side of the equal sign. We can do that by subtracting x from both sides.
3 = x² +2x
Now, add the square of half the x-coefficient.
3 +1 = x² +2x +1
(x +1)² = 4 . . . . . . . . write as a square in the desired form
__
To solve, take the square root, and add the opposite of the left-side constant.
x +1 = ±2
x = -1 ±2 . . . . . . matches choice (D)
Answer: B) 56
Just multiply all numbers and see which number from the choices match your answers after doing the multiplication! Hope I helped!
Answer:
V = 972m^3
Step-by-step explanation:
small = lwh = 9(2)(6)
large = lwh = 16(9)(6)
V = 9(2)(6) + 16(9)(6)
V = 108 + 864
V = 972m^3
