Answer:
x = -23 and -2
Step-by-step explanation:
We can say;
<em>(x + 23) = 0</em>
<em>(2x + 4) = 0</em>
Therefore let's solve the first equation first;
(x + 23) = 0
x + 23 = 0
x = 0 - 23
<u>x = -23</u>
Now let's solve for the second equation;
(2x + 4) = 0
2x + 4 = 0
2x = 0 - 4
2x = -4
x = -4/2
<u>x = -2</u>
Hope this helps!
Answer:
(4x - 11i)(4x -+11i)
Step-by-step explanation:
Factor as a difference of squares
a² - b² = (a - b)(a + b)
note that i² = - 1
Given
16x² + 121
= (4x)² - (11i)²
= (4x - 11i)(4x + 11i)
Answer:
There are the only triangles with right angles
Step-by-step explanation:
September : 12
october: 18
november : 16
together in sept. and oct. = 12+18 = 30
