Answer:
C
Step-by-step explanation:
The picture is a bit blurry, but from what i can see, i'd say C (whichever one has -4 x 3 x 1 under the square root.)
So for this, you need to know the quadratic formula, which is:
<em>*ignore the weird capital A, it keeps coming up when i try to use the ± symbol</em>
They have given you the equation of a quadratic, so the first thing you have to do is rearrange it, so that 
comes first.
<u>So now we have the equation: 3</u><u> - 2x +1</u>
*the quadratic formula uses a, b and c, but they are specific. a is always the coefficient of , b is always the coefficient of x and c is always the constant (number without an x)
<u>So, i can find that, in this case:</u>
a = 3 b= -2 c=1
<u>Now substitute each of those values it into the original quadratic equation:</u>
<u />
<em>*again, ignore the weird capital A. </em>
That's how you find the answer, which from what i can tell in the picture is C.
Hope that helped : )

Answer:
158cm
Step-by-step explanation:
Data obtained from the question. This includes:
Height of first snow ball (H1) = 7/10m
Height of 2nd snow ball (H2) = 1/2m
Height of 3rd snow ball (H3) = 38cm
Total height of snow man (HT) =?
Next we shall covert from m to cm.
This is illustrated below:
For the first snow ball
1m = 100cm
7/10m = 7/10 x 100 = 70cm
For the 2nd snow ball:
1m = 100cm
1/2m = 1/2 x 100 = 50cm
Now we can obtain the height of the snow man as follow:
Height of first snow ball (H1) = 70cm
Height of 2nd snow ball (H2) = 50cm
Height of 3rd snow ball (H3) = 38cm
Total height of snow man (HT) =?
HT = H1 + H2 + H3
HT = 70 + 50 + 38
HT = 158cm
Therefore the height of the snow man in cm is 158cm
His friends ate 1/2 of 3/4..." of " means multiply
1/2 * 3/4 = 3/8
so his friends ate 3/8 of the bag of popcorn
The answer is b. Plug in y and simplify the question
