Answer:
m=a/x+Q
Step-by-step explanation:
Q=m-a/x
To solve this we need to isolate m so we will bring -a/x to the other side of the equal sign so it will become positive i.e. ax now will be written as a/x+Q=m
in other wards m=a/x+Q
You use the formula C=2(3.14)r r is the radius and in this situation 2 so the answer will be 12.56
Her piece of lace was 80 cm.
2(14)+2(20)+12
28+40+12
=80
There are 8 tens in the number 1,384.
Each digit in the number has an equivalent value based on its placement in the number.
1,384 where:
1 is in the thousands value
3 is in the hundreds value
8 is in the tens value
4 is in the ones value
The extended form of 1,384 is:
1 x 1000 + 3 x 100 + 8 x 10 + 4 x 1 = 1,384
1,000 + 300 + 80 + 4 = 1,384
8 x 10 = 80 ; shows that there are 8 10s in the number with a product of 80.
Each of these roots can be expressed as a binomial:
(x+1)=0, which solves to -1
(x-3)=0, which solves to 3
(x-3i)=0 which solves to 3i
(x+3i)=0, which solves to -3i
There are four roots, so our final equation will have x^4 as the least degree
Multiply them together. I'll multiply the i binomials first:
(x-3i)(x+3i) = x²+3ix-3ix-9i²
x²-9i²
x²+9 [since i²=-1]
Now I'll multiply the first two binomials together:
(x+1)(x-3) = x²-3x+x-3
x²-2x-3
Lastly, we'll multiply the two derived terms together:
(x²+9)(x²-2x-3) [from the binomial, I'll distribute the first term, then the second term, and I'll stack them so we can simply add like terms together]
x^4 -2x³-3x²
<u> +9x²-18x-27</u>
x^4-2x³+6x²-18x-27
