A variable is an unknown number or value represented by a letter.
For example find the missing variable:
2x - 3 = 9
<span>The number in exponential notation for the product of plural consisting only of Unity (Cyfra at the construction site of Unity 1.9 ) and decimal parts and plural 10 raised to do the appropriate Powers .
</span>0,02 59
<----|
* 100 = 10²
0,0259 = 2,59* 10⁻²
........................................
5,5820
5,5820*10⁰
........................................
0,009 73
<------|
*1000 = 10³
0,00973 = 9,73*10⁻³
.........................................
8 56

: 100 = 10²
856 = 8,56 *10²

* 10 000 = 10⁴
7,2 * 10⁻⁴
....................................
0,001 216
<------|
* 1000 = 10³
1,216 * 10⁻³
Answer:
Explanation:
P = 2(W + L)
L = 2x - 3
W = x + 4
P = 2[(x + 4) + (2x - 3)]
So thats the expression for the perimeter
1-b cuz its describing numbers
2-A-prmation again
3-7C5 = 7!/(5!2!) = 7*6/2 = 21 so its B
4-792
5-d
hoped i helped
