Answer:
19+23
Step-by-step explanation:
You can use Pick's theorem, where:
Area = Number of interior points (points inside the polygon) +

· Number of boundary points (points on the polygon's perimeter) - 1
so:
1.Yellow:
Interior points = 3
Boundary points = 8

2. Red:
Interior points = 2
Boundary points = 10
Answer:
x = 3
Step-by-step explanation:
6x+ 5 = 3x + 14
Subtract 3x from both sides
6x+ 5 -3x = 3x + 14 - 3x
Simplifying
3x + 5 = 14
Subtract 5 from both sides
3x + 5 - 5 = 14 - 5
Simplifying
3x = 9
Divide both sides by 3
3x/3 = 9/3
Simplifying
x = 3
Answer:

Step-by-step explanation:
Standard form of a linear equation: 
(where A, B and C are integers, and A shouldn't be negative)
Given equation:

Multiply both sides by 8:


Subtract 8y from both sides:


Subtract 24 from both sides:


In standard form:

Question 4.
The multiples of 7 are those numbers obtained from the product of 7 and a whole number.
The multiples of 7 between 50 and 70 are:

You could be 56 or 63
