<em>t</em> = 0 belongs to the interval [-3, 3] (since -3 ≤ 0 ≤ 3 is true), so use the middle function to evaluate <em>h</em> (0):
<em>h</em> (0) = 0 × (0 + 4) = 0
X = 180 - 42 - 73 = 65 degrres
y = 180 - 131 = 49 degrees
< z = 65 + 49 = 114 degrees (answer).
X=12.5
If the perimeter is 90
90=3x+3x+15
Combine like terms
90=6x+15
Subtracts 15 from both sides
75=6x
Divide by six to get x by itself
12.5=x

Answer:
Correct answer's the top one
Step-by-step explanation:
Think of powers of 10. Each power is 10 times larger or smaller than the last one. So in this instance, the bacterium has a diameter of 10^-6 which is 1 millionth. And then there's the virus, which has a diameter of 10^-7 which is 1 ten millionth. So basically, take 10^-7 and times that by 10. This gives you 10^-6, which can only mean that the bacterium is 10 times <u>bigger</u> than the virus, which is the answer on top.
