1. the answer is b = 30 .... you first simply both sides of the equation then flip it then multiply both sides by 10/13
2. the answer is g = 3/2 ...... multiply both sides by 5/2
Answer: -12
Step-by-step explanation: It just is man i think
Answer:
Perimeter- 26cm
Area- I Don't know sorry. I'll comment if I figure it out
The little lines in each side show that the sides are the same length but you also need to find the length of the smaller side which isn’t the same. For this imagine that the shape is split into a square and a triangle and you need to find the long side of the triangle using Pythagoras
a^2 + b^2 = c^2
20^2 + 20^2 = 800
Square root of 800 = 28.3
Then do 28.3-20=8.3
So I think the answer is 20+20+20+20+20+8.3=108.3 cm
