Answer:
x = 64/5
Step-by-step explanation:
34x+85=3(13x+7)
<u><em>Step 1: Simplify both sides of the equation.</em></u>
<em />
34x+85=3(13x+7)
34x+85=(3)(13x)+(3)(7)(Distribute)
34x+85=39x+21
<u><em>Step 2: Subtract 39x from both sides.</em></u>
<u><em /></u>
34x+85−39x=39x+21−39x
−5x+85=21
<u><em>Step 3: Subtract 85 from both sides.</em></u>
<em />
−5x+85−85=21−85
−5x=−64
<u><em>Step 4: Divide both sides by -5</em></u><em>.</em>
<em />
−5x/−5=−64/−5
x=64/5

Answer:
x = 2
Step-by-step explanation:
Using Pythagoras identity in the right triangle
x² = 10² + 6² = 100 + 36 = 136 ( take the square root of both sides )
x = 
= 
= 2

You really should spend the time. Math is used everywhere.
4x²-5=3x+4
4x²-3x-9=0
x=(3±√((-3)²-4*4*-9))/2*4
x=3±√(9+144) /8
x=(3±√153) /8
x=⅜±√153/8
The roots of the parabola is where the x-intercepts are so the answer is x=-1 and x= 5
