mj thinks of a number. she adds 2 to the number then multiples the result by 3. The answer is the same as adding 5 to the number them multiplying by 2
my number is d
3 (d×2) = 2 (d+5)
3×d + 3×2 = 2×d + 2×5
3d + 6 = 2d + 10
3d +6 -6 -2d = 2d - 10 - 6
3d - 2d = 10 - 6
d = 4
The area of the rectangle is
3x4=13
The area of the triangle is 4
The total area will be 13+4=17
The side lengths on the new dilated rectangle will be 30cm and 16cm
<h3>How to calculate dilation</h3>
Given the following parameters
- Length = 8cm
- Breadth = 15cm
If the length and breadth are dilated by a factor of 2, hence the new dimansion will be:
New length = 2(15) =30cm
New width =2(8) = 16cm
Hence the side lengths on the new dilated rectangle will be 30cm and 16cm

M<1 = 180°-66°-84°
= 30°
m<3 = 180°-84°
= 96°
m<2 = 180°-96°-43°
= 41°
