What 2 numbers multiply to -35 and add to -2
the bigger factor is negative since they add to a negative number
add factors, bigger one is negative
1-35=-34, nope
5-7=-2, yep
(x+5)(x-7)
T= 34
Explanation
So measure t equals measure s also since it’s a isosceles triangle!
Then we combine all the equations together and set it equal to 180 because every triangle is 180°.
3x-2 + 3x-2 + 9x+4 = 180
Now we combine like light terms
3x + 3x + 9x -2 -2 +4 = 180
15x= 180
Now that we simplify the equation we solve for x
15x/15= 180/15. Divide both sides by 15
X= 12
The problem ask what the measure of t is so we plug the 12 into the equation to find the measure
3x-2= 3(12)-2
36-2= 34
So the measure of t is 34°
I hope this helped pls mark as brainliest
Is there a story for this question??
The correct answer is the second one: ±√15/3
Explan ation:
You have the quadratic equation <span>3x^2−10=−5. Then you must clear the variable "x" as below:
</span><span>
3x^2−10=−5</span>
<span> 3x^2=−5+10
</span><span>3x^2=5
</span><span>x^2=5/3
x=</span>±√(5/3)
When you multipy the numerator and the denominator by 3 for simplify the result, you obtain:
x=±√(5x3/3x3)
x=±√(15/3²)
When you simplify, you have:
x=±√15/3
