Question 4: -11
Question 5: -7
Step-by-step explanation:

Every triangle has 180 degrees.
So all three angles add to 180
<em><u>Equation</u></em>
60 + 80 + x + 51 = 180
<em><u>Solution</u></em>
Combine the like terms on the left. This is the first time I've seen x be a negative value. Almost all of the time it isn't, which should make you wonder.
191 + x = 180
Subtract 191 from both sides.
191 - 191 + x = 180 - 191
x = - 11

If a triangle is a right triangle and one of the angles is 45, then so is the other one.
<em><u>Proof</u></em>
a + 45 + 90 = 180 Combine like terms on the left
a + 135 = 180 Subtract 135 on both sides.
a + 135-135=180-135 Combine the like terms
a = 45
<em><u>Statement</u></em>
That means 52 + x = 45 and here is another negative answer. Subtract 52 from both sides
52 - 52 + x = 45 - 52 Combine like terms.
x = - 7
Hey fellow Army.
So because JKLM=PQRS, that means that all the line segments are equal.
JK=PQ=6.4
KL=QR=13
LM=RS=9
MJ=SP=18
Okay now for the graph.
It was first reflected over the y axis, and then shifted over vertically by 9 .
Hope this helps. Have a good day!
Because there is no solution if any number divide by 0
Answer:
<em>The population on 30th day will be </em><em>134836</em><em>.</em>
Step-by-step explanation:
This is a case of exponential growth. The general form of exponential function is,
where, a and b are constants.
The data points from the question are 
Putting the values in the function,
for 
----------1
for 
------2
Dividing equation 2 by 1,
Putting the value of b in equation 1,
Now the function becomes,
Putting x=30, we get
