You need to use the distributive property. So you take the -9 from outside the parentheses and multiply itself by the numbers inside.
Answer:
8xyz
Step-by-step explanation:
multiply all numbers and alphabets
- 288xyz, 2.360xyz, 3.648xyz
- find HCF of numbers and after multiply by xyz
- 288={2×2×2×31}
- 360={2×2×2×3×3×5}
- 648={2×2×2×3×3×3×3}
- HCF={2×2×2}xyz
- 8xyz
Given that-
√(0.09×0.09×x) = 0.09×0.09×√z
On squaring both sides then
⇛[√(0.09×0.09×x) ]² = (0.09×0.09×√z)²
⇛ 0.09×0.09×x= (0.09)²×(0.09)²×(√z)²
⇛ (0.09)² × x = (0.09)²×(0.09)²×z
⇛ (0.09)² × x/z = (0.09)²×(0.09)²
⇛x/z = (0.09)²×(0.09)²/(0.09)²
⇛x/z = (0.09)²
⇛x/z = 0.09×0.09
⇛x/z = 0.0081
<u>Answer</u><u>:</u><u>-</u> Hence the value of x/z will be 0.0081 r respectively.
Let's say the number of days is d (as stated in the question). there are always 24 hours in a day, so the amount of hours in d days has to be 24*d. since you also have the six hours, this can be written as 24*d + 6 = the number of hours in d days and six hours.
