We can check each of these using the Pythagorean Theorem, $a^2 + b^2 = c^2$
Option A:
$.5^2 + 1.2^2 = 1.3^2

$
.25 + 1.44 = 1.691.69 = 1.69
This option works
Option B
$1^2 + 2^2 = 3^2$
1 + 4 = 9
5 ≠ 9
This option does not work, but let's check the others to make sure
Option C:
$6^2 + 8^2 = 10^2$
36 + 64 = 100
100 = 100
This option works
Option D:
$3^2 + 4^2 = 5^2$
9 + 16 = 25
25 = 25
This option works

So, after doing the calculations, we see that option B does not work

What is the factored form x^3 - 1 ?

amid [387]

Answer: x^3 - 1 = (x - 1)(x^2 + x + 1)

Explanation:

This is a type of factorizing called the sum or difference of 2 cubes:

a^3 - b^3 = (a - b)(a^2 + ab + b^2)

The sum of the cubes is factored as:

a^3 + b^3 = (a + b)(a^2 - ab + b^2)

In this case, we have: x^3 - 1 so follow the rule above.

x^3 - 1 = (x - 1)(x^2 + x + 1)

3x + 5y = 7 How to solve it

Lubov Fominskaja [6]

Answer:

x=1 and y=4/5

Step-by-step explanation:

Given system of equations

3x+5y=7

5x+10y=13

Multiply first equation by 2

2(3x+5y)=2(7)

6x+10y=14

Eliminate y-variable to get "x"

6x+10y=14

- 5x+10y=13

x = 1

Substitute x=1 into either equation and find "y"

3x+5y=7

3(1)+5y=7

3+5y=7

5y=4

y=4/5

Therefore, x=1 and y=4/5
