3 + 1/9 = 27/9 + 1/9 = 28/9
2 + 2/5 = 10/5 + 2/5 = 12/5
------------------------------------------
So:
[3+(1/9)]/[2+(2/5)]
=(28/9)/(12/5)
=(28/9)*(5/12)
=140/108 = 70/54 = 35/27
Answer:
a. (3-7x) + (3-7x) + (3-7x) + (3-7x)
b. 4(3-7x)
c. 12 - 28x
Step-by-step explanation:
To find the perimeter of a square, you need to add up all the sides
a. Since a square has all equal sides you will need to write the expression four times: (3-7x) + (3-7x) + (3-7x) + (3-7x) = perimeter
b. Expressing this as a product, we can condense the formula to 4 multiplied by the expression since it is written four times: 4(3-7x) = perimeter
c. Using the distributive property, we can write the product 4(3-7x) from b. as: (4)(3) + (4)(-7x) = 12 + (-28x) = 12 - 28x = perimeter

The missing information of the triangle is C = 63°, b ≈ 28.084 and c ≈ 25.084. (Correct choice: C)
<h3>How to determine the missing sides and angles</h3>
In this question we have a triangle with a known <em>side</em> lengths and two known <em>angle</em> measures. First, we find the missing angle by <em>Euclidean</em> geometry:
C = 180° - 94° - 23°
C = 63°
Lastly, we determine the <em>missing</em> sides by law of sines:
b ≈ 28.084
c ≈ 25.084
The missing information of the triangle is C = 63°, b ≈ 28.084 and c ≈ 25.084. (Correct choice: C)
