the area is about 41.033ft2
Answer:
-4
Step-by-step explanation:
We have the coordinates (6, 3) and (8, 4), allowing us to calculate the slope (or gradient). To do this, you divide the change in y by the change in x, which is 1/2 which is a half.
The form of a linear equation is y = mx + c, where m is the gradient and c is the y-intercept.
We have the gradient, so we can put it in the equation:
y = x/2 + c
We can now substitute in a pair of our coordinates and rearrange to find the y-intercept.
3 = 6/2 + c
3 = 3 + c
c = 0
Therefore the equation for our line is y = x/2.
We can now put in the y coordinate we were given to work out the corresponding x coordinate:
-2 = x/2
x = -4
Therefore n is -4.
Answer:
√12 = irrational number
Step-by-step explanation:
Irrational numbers are decimals that are non-terminating (don't stop) and non-repeating (don't have a pattern). Non-perfect squares, or square roots that do not have a factor that is multiplied by itself, when solved it will produce a non-terminating, non-repeating decimal:
√12 = 3.464101...
180-115=65
65+70=135
180-135=45
SO C.45
