It would be 0.38 the 8 is repeating
Answer:
114
Step-by-step explanation:
so lets call shelf 1 x
shelf 2 is twice size + 18 of shelf 1 so it is 2(x)+18
shelf 3 is 12 less than shelf 1 so x-12
shelf 4 is four more so x+4
Add them all together and it should be 5x+10= 2.5 m or 250 cm
Solve for x using cm
then plug into shelf 2 equation

Answer:
x = 4, x = 8
Step-by-step explanation:
To find the roots equate to zero, that is
- x² + 12x - 32 = 0 ( multiply through by - 1 )
x² - 12x + 32 = 0
Consider the factors of the constant term (+ 32) which sum to give the coefficient of the x- term (- 12)
The factors are - 4 and - 8, since
- 4 × - 8 = + 32 and - 4 - 8 = - 12, thus
(x - 4)(x - 8) = 0
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x - 8 = 0 ⇒ x = 8
