-9+4=5 because two negative signs makes a positive
If the last two digits of the number are divisible by four
The ratio of the area of the <u>first figure</u> to the area of the <u>second figure</u> is 4:1
<h3>Ratio of the areas of similar figures </h3>
From the question, we are to determine the ratio of the area of the<u> first figure</u> to the area of the <u>second figure</u>
<u />
The two figures are similar
From one of the theorems for similar polygons, we have that
If the scale factor of the sides of <u>two similar polygons</u> is m/n then the ratio of the areas is (m/n)²
Let the base length of the first figure be ,m = 14 mm
and the base length of the second figure be, n = 7 mm
∴ The ratio of their areas will be
![(\frac{14 \ mm}{7 \ mm})^{2}](https://tex.z-dn.net/?f=%28%5Cfrac%7B14%20%5C%20mm%7D%7B7%20%5C%20mm%7D%29%5E%7B2%7D)
![= \frac{196 \ mm^{2} }{49\ mm^{2} }](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B196%20%5C%20mm%5E%7B2%7D%20%7D%7B49%5C%20mm%5E%7B2%7D%20%7D)
![=\frac{4}{1}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B4%7D%7B1%7D)
= 4:1
Hence, the ratio of the area of the <u>first figure</u> to the area of the <u>second figure</u> is 4:1

Answer:
20
Step-by-step explanation:
This sequence follows a pattern of doubling then subtracting by two. The last action was 12 to 10, which is subtracting by two, so the next must be multiplying by 2.
<span>4 hundreds 13 tens 5 ones = 400+13*10+5
= 400+130+5
= 535</span>
