Answer:
x=(T-2y)/2
Step-by-step explanation:
Answer:
x² - x - 6
Step-by-step explanation:
Step 1: Write expression
(5x² + 2x - 5) - (3x² + 3x + 1)
Step 2: Distribute negative
5x² + 2x - 5 - 3x² - 3x - 1
Step 3: Combine like terms (x²)
2x² + 2x - 5 - 3x - 1
Step 4: Combine like terms (x)
x² - x - 5 - 1
Step 5: Combine like terms (constants)
x² - x - 6
Hey there! This is gonna require the Pythagorean Theorem which is<span> a^2 + b^2 = c^2
</span>
a and b in this case are the legs while c is the hypotenuse! So, we can just plug in the numbers we know!
3^2 + 10^2 = c^2
9 + 100 = c^2
109 = c^2
And then take the square root of 109 to get the hypotenuse.
<span>10.4403065089 = c
</span>
Since we need to round to the nearest hundredth, though, it would be 10.44
I hope that helps! Feel free to let me know if you have any questions!

Answer:
x=15
Step-by-step explanation:
These angles are corresponding angles and with parallel lines corresponding angles are equal
9x+19 = 10x+4
Subtract 9x from each side
9x+19 -9x = 10x+4-9x
19 = x+4
Subtract 9 from each side
19-4 =x
15=x
