Answer:
<em><u>X=-8 B if i can get brainliest that would be great</u></em>
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4(2x+1)=6x−12
(4)(2x)+(4)(1)=6x+−12(Distribute)
8x+4=6x+−12
8x+4=6x−12
Step 2: Subtract 6x from both sides.
8x+4−6x=6x−12−6x
2x+4=−12
Step 3: Subtract 4 from both sides.
2x+4−4=−12−4
2x=−16
Step 4: Divide both sides by 2.
2x/2=−16/2
x=−8
Answer:
x=−8
Answer:
-3
Step-by-step explanation:
19-13=6+1=7-14=-7+4=-3
2x^2+8x-12=0
with form
ax^2+bx+c=0
move c to the other side
2x^2+8x=12
x^2 is multiplied -> divide equation by 2
x^2+4x=6
complete square:
divide b=4 by 2
4*1/2=2
square 2
2^2=4
add 4 to both sides
x^2+4x=6
x^2+4x+4=6+4
x^2+4x+4=10
transform to polynom
(x+2)^2=10
this left side is option B multiplied by a factor of 16 and therefore equal:
(4x + 8)^2
(4*4)x^2+(4*2*8)x+8*8
16x^2+64x+64
x^2+4+4
bonus: calculate root
x+2=+/-sqrt(10)
x=-2+/-sqrt(10)
so it is option B
Answer:
52%
Step-by-step explanation:
First, find the difference between this year's sales and the previous'. 1500-990=510.
Now we can divide 990 by 510 to find the percent increase. 510/990=0.515151515152, or 52%.
