Answer:
2 and 3/8
Step-by-step explanation:
4/6 = 6/8 so 5/8 + 6/8 = 2 and 3/8
Hello,
Well first, to get a fraction into a decimal you have to divide the fraction. I was taught since the 2 is the numerator, it gets divided out of and the 9 is what you're dividing the 2. You may know this already but the correct answer is 0.22. 2/9 = 0.22. I hope this helps
Answer:
(3p+7.75)-(3.65+2p)
Step-by-step explanation:
I'm pretty sure that's the expression
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
