Answer:
The second one, my order is different, but they are equivalent answers
Step-by-step explanation: 6 22 22 18
(√6 + √11) / (√5 +√3) multiple top and by (√5 - √3) note the minus
(√6 + √11) × (√5 - √3) / (√5 +√3) x (√5 - √3)
(√30 + √55 - √18 - √33) / (5 - 3)
(√30 + √55 - 3√2 - √33) / 2
Answer:
Step-by-step explanation:
I can barely see enough to do 5 and 6. 7 the diagram is unclear and 9 I can't tell where the letters are. I suggest you darken the lines and make sure the letters for the unknowns are clear. Don't hold the paper: just as the picture was taken the image moved slightly. I don't know what to suggest.
Five
The ray defining a is pointing right at the five. That's my first assumption.
You need to find the interior angle connected to a.
Pentagon exterior angles
The total number of degrees for the exterior angles of a pentagon is 360
<em><u>Supplement of 140 degrees</u></em>
140 + x = 180 because the exterior and interior angles are supplementary
x = 180 - 140
x = 40
<em><u>Find a</u></em>
a + 40 + 60 + 84 + 68 = 360
a + 252 = 360
a = 360 - 252
a = 108
Six
This is really hard to read. Including b, there are three angles that are marked the same
Supplement to 68
180 - 68 = 112
Find b
112 + 43 + x + 89 + x +x = 360
244 + 3x = 360
3x = 116
x = 116/3
x = 38.67
Since b is marked as equal to 1 of the 3 exterior angles that are equal, b = 38.67
That is all I can read.
Answer:
.071 times 101
Step-by-step explanation: The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.

Answer:</h2>
<em>Question 1)</em>
5x
<em>Question 2) </em>
0.22a
<em>Question 3)</em>
8 + 6n
<em>Question 4)</em>
25
<em>Question 5) </em>
ab+c=14
<h2>
Step-by-step explanation:</h2>
<u>Ques 1)</u>
The product of 5 and x.
Product of two numbers means that it is obtained by multiplying them.
Hence, the expression so obtained is: 5x
<u>Ques 2)</u>
22% of a
It means that:
22%×a
Also, we know that:
22% =0.22
This means that:
22% of a=0.22×a
i.e.
22% of a=0.22a
<u>Ques 3)</u>
8 more than the product of 6 and n.
The product of 6 and n is given by: 6n
and 8 more than there product will be given by:
8+6n
<u>Ques 4)</u>
Evaluate: 30 − m/6 for m = 30
i.e. we put m=30 in the expression and get the resulting value.
i.e. we have:
30-m/6=30-(30/6)
i.e.
30-m/6=30-5
i.e.
30-m/6=25
<u>Ques 5)</u>
Evaluate ab + c for a= 2, b = 5, c = 4.
i.e. we will put the value of a,b and c in the given expression and find the value.
i.e.
2×5+4= 10+4
i.e.
ab+c=14
