To set up an equation correctly, it is important to understand the problem statement and the given values. We do as follows:
initial number of balls = 14 + 23 = 37
number of baseballs per box = 12
number of tennis balls per box = 16
we let x as the number of boxes
Total number of balls = 37 + 12x + 16x
Total number of balls = 37 + 28x
Answer:
around 13.18
Step-by-step explanation:
the middle square is 2*2 = 4
the triangle then is 2^2 + 6^2 = 40 -> sqrt40 = 6.325
and then 2^2 + 2^2 = 8 -> sqrt8 = 2.828
4+6.325+2.828 = 13.18
Answer: The slope will be 1/2
Step-by-step explanation: If you plot the two coordinate points on a graph and connect it with a line, you will have 1/2 as you rise/run (or slope)
(x + y)² and z² + 4(1/2 xy) both represent the area of the outer square and are equal.
Step-by-step explanation:
- Step 1: The below reasons explain why the expression is a true equation.
1. The expression (x + y)² finds the area of the outer square by squaring its side length.
[In the figure, side length of the outer square = x + y and area of a square = (side length)²]
2. The expression z² + 4(1/2 xy) finds the area of the outer square by adding the area of the inner square and the four triangles.
[In the figure the length of the inner square is z, the triangles have a base x and height y and area of a triangle = 1/2 base × height]
⇒ So the left hand side and right hand side of the expression is equal.
