Números que suman 6:
3 + 2 + 1 = 6=> 3^2 + 2^2 + 1^2 = 9 + 4 + 1 = 14
4 + 3 - 1 = 6 => 4^2 + 3^2 + (-1)^2 = 16 + 9 + 1 = 26 => do not use negative numbers, because that will increase the other numbers.
5 + 1 + 0 = 6 => 5^2 + 1 + 0 = 25 + 1 + 0 = 26
4 + 2 + 0 = 4^2 + 2^2 + 0 = 16 + 4 = 20
When you use zero the you increase the sum of the squares.
Then the three numbers that yields the minimum sum of the squares is 1, 2 and 3.
Answer:
x=4 (solution) x=-14 (extraneous solution )
Step-by-step explanation:
|x+5|=9 -------original equation
Equation can be equal to +9 and -9
x+5 =9 x+5 =-9
x= 9-5 x=-9-5
x=4 (solution) x=-14 (extraneous solution )
for checking
x+5 = 9 x + 5=9
4+5= 9 -14+5=9
9=9 -9=-9
50+55x=y 200+45x=y
We have a system of equations.
The answer is 875€ both in 15 months. It will take 15 months.
Answer:
D 0.00009
Step-by-step explanation:
9 × 10^-5 = 9 × 1/10^5 = 9 × 1/100,000
= 9 × 0.00001
= 0.00009

<em>Comment on place value</em>
The exponent of 10 associated with the place value in a decimal number increases from 0 to the left of the decimal point, and decreases from -1 to the right of the decimal point:
100. = 10²
10. = 10¹
1. = 10⁰
0.1 = 10⁻¹
0.01 = 10⁻²
0.001 = 10⁻³
0.0001 = 10⁻⁴
0.00001 = 10⁻⁵
This simple realization can help you immensely with scientific notation.
The perimeter would also be 18 square feet
