Answer:
The distributive property teaches us how to properly multiply in examples like the answer I have given.
In my example : 2 * (4 + 12x) = 8 + 24x
We would take the 2 that is on the outside of the equation in the parenthesis and multiply it first with the 4, and then with the 12x. This results in 8 + 24x.
A simplified version would be to just remove the x.
When we do that we see that 8 + 24 is equal to 32.
What it also demonstrates is that:
2 * (4 + 12) is the same as saying 8 + 24, both equal 32.

Answer:
see below
Step-by-step explanation:
In decimal, the values of the fractions are ...
-0.2 = -0.200
-3/7 = -0.429
-2/8 = -0.250
So, in a, b, c order, they are ...
a = -3/7
b = -2/8
c = -0.2
Answer: 729
Step-by-step explanation:
Move items with negative exponents from numerator to denominator or vice versa and change sign of exponent. Factorize composite numbers, say 10^3 = 2^3 × 5^3 and 81 = 3^4. Combine factors with same base, adding exponents. Cancel factors appearing in both numerator and denominator, subtracting exponents.
5^-3×6^-5×81×4/(3^-7×10^-3)
= 3^7×10^3×81×4/(5^3×6^5)
= 3^7×2^3×5^3×3^4×2^2/(5^3×2^5×3^5)
= 2^5×3^11×5^3/(2^5×3^5×5^3)
= 3^6
= 729
We can solve for the surface area of the triangular prism using the formula below:
SA=bh + (s1+s2+s3) H
where b for the base, h and H for the height while s1, s2 and s3 for the length of the sides of the equilateral triangles.
Solution is shown below:
SA=10*9+(10*10*10) *18
SA=90+(1000*18)
SA=1,620,000 u²
12/15 = 8/x
Cross multiply:
12*x = 8*15
⇒ 12*x= 120
⇒ (12/12)*x = 120/12
⇒ x= 10.
Final answer: x=10.
Hope this helps~
