Answer:
the equation is y = ax + b (a ≠ 0)
see in the graph, the line passed through (0;3) and (1;5)
=>b = 3
a + b = 5
<=> a = 2
b = 3
=> the equation is y = 2x + 3

Answer:
21.46 cm²
Step-by-step explanation:
So we need to find the r for the circle
r=10/4=5/2
so the area of one circle is Ac=πr²
Ac=π(5/2)²=25/4π
and there are 4 of them: 25/4π*4=25π=78.54
the area of square is 10²=100
100-78.54=21.46 cm²
