Answer:
If I am right you have to multiply 8 by 30 and than divide it by 12 the answer it will give you is x
On your paper, you wrote down a^2+b^2 = c^2 which is the pythagorean theorem
You are on the right track. You'll use this equation. In this case
a = 36
b = 18
c = 43
The value of a and b can be swapped. The value of c is always the longest side.
Let's see if a^2+b^2 = c^2 is true or not
a^2 + b^2 = c^2
36^2 + 18^2 = 43^2
1296 + 324 = 1849
1620 = 1849
The last equation is false so the first equation is false when a = 36, b = 18 and c = 43
We do NOT have a right triangle so we do NOT have a rectangle
Answer: No, the table is not "square" (ie, have right angles at the corners)

Answer:
- 0.404 . . . cm/day
- the average growth per day in cm
Step-by-step explanation:
The slope is the x-coefficient in the equation, 0.404.
The slope is the rate of change of the dependent variable (height) with respect to the independent variable (number of days). In this case, it is the average increase in the plant's height each day, in cm.
Answer:
y = 2x +13
Step-by-step explanation:
1. find the slope by using the formula y2-y1
--------
x2-x1
which is
23 - 19 4
------------ = --- = 2
5-3 2
2. finding the y intercept
so to find the y intercept you plug in the numbers to this formula
y-y1 = m (x-x1)
y - 19 = 2 (x -3)
y - 19 = 2x -6
+19 +19
y = 2x +13
