Answer:
X=6
Step-by-step explanation:
5(x+2)=6x+3x−1
<u><em>Step 1: Simplify both sides of the equation.</em></u>
5(x+2)=6x+3x−14
(5)(x)+(5)(2)=6x+3x+−14(Distribute)
5x+10=6x+3x+−14
5x+10=(6x+3x)+(−14)(Combine Like Terms)
5x+10=9x+−14
5x+10=9x−14
<u><em>Step 2: Subtract 9x from both sides.</em></u>
5x+10−9x=9x−14−9x
−4x+10=−14
<u><em>Step 3: Subtract 10 from both sides.</em></u>
−4x+10−10=−14−10
−4x=−24
<u><em>Step 4: Divide both sides by -4.</em></u>
−4x / -4= −24 / −4
x=6
Answer:
y= (2-√3x+√3)(2+√3x-√3)
Step-by-step explanation:
hello:
use identity : a²-b²=(a-b)(a+b)
y=-3(x-1)^2+4 = 2²- (√3(x-1))²= 2²-(√3x-√3)² = (2-√3x+√3)(2+√3x-√3)
145. 7 + 8 is 15 carry the 1, 9+4+1 is 14, so 145
