8x-12=36
Let's solve your equation step-by-step.
<span><span><span>8x</span>−12</span>=36
</span>Step 1: Add 12 to both sides.
<span><span><span><span>8x</span>−12</span>+12</span>=<span>36+12
</span></span><span><span>8x</span>=48
</span>Step 2: Divide both sides by 8.
<span><span><span>8x/</span>8</span>=<span>48/8
</span></span><span>x=6
</span>Answer: x=6
All of these would be perfectly fine represented by a pie chart except A, which doesn't add to 100%.
The question seems to be getting at the idea that a pie chart might be better when the slices are all visually different sizes. I don't really think that's right; a pie chart for D say, where the two slices are about the same, gives the correct impression of the relative frequencies, which are about the same.
Answer they're looking for: C
Y = 2x² + 30x + 200
y = 2(x² + 15x + 100)
x² = x*x
100 ⇒ 1 x 100 ; 2 x 50 ; 4 x 25 ; 5 x 20 ; 10 x 10
200 = 2x² + 30x + 200
0 = 2x² + 30x + 200 - 200
0 = 2x² + 30x + 0
0 = 2(x² + 15x + ?)

Answer:
x= 7/ 8 is the answer
If you wanted to simplify
Answer:
3039007
Step-by-step explanation:
V= 13
Substitue (v) for 13
7253(8*4(13))
Go by the rules be PEMDAS
First you the parentheses
4 times 13= 52
52 times 8= 416
Now you just multiply the two numbers
416 times 7253= 3039007
