Answer:
(x/12)
Step-by-step explanation:
if 12 pieces combine to make x, [we know they are identical], each piece must be 1/12 of x [1/12·x = x/12]
(think of it like this: "x" length must be divided amongst 12 pieces, so, we divide x/ 12)
Timber=x/12
12 pieces long is x, if the length of each one is same, so the length of each one is x/12.
the third answer
c = 4
c + 1 = 1 + 1 + 1 + 1 + 1
4 + 1 = 1 + 1 + 1 + 1 + 1
5 = 5
6^8
6^4 * 6^4
We know that a^b * a^c = a^( b+c)
6^(4+4)
3² + 6 × 2² - 4² ÷ 2³ = 31.
