Answer:
5
Step-by-step explanation:
10 * 5 = 50
44x + 55x + 77x = 6,464 centimeters.
x =

OR maybe that's another of those infamous Brainly typos.
4x + 5x + 7x = 64 centimeters.
x = 8
Therefore the sides are
4*8 = 32
5*8 = 40 and
7*8 = 56 centimeters

Answer:
- x = 4 is the only real zero
Step-by-step explanation:
<u>Find the zero's of f(x)</u>
- 2x³ - 12x² + 20x - 16 = 0
- x³ - 6x² + 10x - 8 = 0
- x³ - 4x² - 2x² + 8x + 2x - 8 = 0
- x²(x - 4) - 2x(x - 4) + 2(x - 4) = 0
- (x - 4)(x² - 2x + 2) = 0
- (x - 4)(x² - 2x + 1 + 1) = 0
- (x - 4)[(x - 1)² + 1] = 0
- x - 4 = 0 ⇒ x = 4, we already know this
- (x - 1)² + 1 = 0 ⇒ (x - 1)² = - 1, no real solution as the square is never negative
