6²÷2(3)+4
Use the order of operations:
GEMDAS (grouping, exponents, multiplication/division, addition/subtraction)
First is grouping.
While there is a number inside parentheses, there aren't any operations in there we have to do first. The 2(3) is just another way to write multiplication. (2×3)
Second is exponents.
We do have an exponent here, 6².
The ² means to multiply something by itself. 6² = 6×6 = 36
Now our expression is 36÷2(3)+4
Next is multiplication/division. We can do these in any order. (either do the ×3 first or the ÷2 first, it doesn't matter)
Let's start at the left with 36÷2, which equals 18. (check: 18×2=36)
Now, we'll do the 18×3 = 54
If we were to do 36(3)÷2 that would work too-- 36×3÷2 = 108÷2 = 54.
Now while you can do these in any order, what you can <em>not</em> do is multiply the dividend 2 by 3. That would give 36÷6 = 6, which is incorrect. It's not something you need to fret over, just go from left to right doing your multiplication/division and you shouldn't ever have this problem.
Now we have 54 + 4 which is clearly 58.
0=4(x²+8x+16)-12
0=4x²+32x+64-12
0=4x²+32x+52
0=x²+8x+13
D=b²-4ac
D=64-52=12
x=(-b-√D)/2a
x=(-b+√D)/2a
x=(-8-2√3)/2= (-2(4+√3))/2= -(4+√3)
AND
x=(-8+2√3)/2=-2(4-√3)/2= -(4-√3)
Answer:
32
Step-by-step explanation:
b^2c^1
Let b=-4 and c= 2
(-4)^2 ( 2)^1
16 * 2
32
Using subtraction, you would take 3,000 and subtract 1968 from it to leave you 1,032. With that number, the answer to your question is "C"
Steve and Chelsea will have the same amount of money on the 12 week. I can’t graph it but I am a little sure that is the answer
