You have to use this equation the a=5, h=4 and b=9 and you should get the answer of 28
Answer:
The equation of the line is 2 x - y + 5 = 0.
Step-by-step explanation:
Here the given points are A( 1, 7) & B( -3, - 1) -
Equation of a line whose points are given such that
( ) & ( )-
y - = ( x - )
i.e. <em> y - 7= ( x- 1)</em>
<em> y - 7 = ( x -1)</em>
<em> y - 7 = 2 ( x - 1) </em>
<em> y - 7 = 2 x - 2</em>
<em> 2 x - y + 5 = 0</em>
Hence the equation of the required line whose passes trough the points ( 1, 7) & ( -3, -1) is 2 x - y + 5 = 0.
Answer: 11
6*2 = 12
5*2=10
10= x - 1
x = 11
Answer:
d = 8.6
Step-by-step explanation:
a^2 + b^2 = c^2
7^2 + 5^2 = c^2
49 + 25 = c^2
74 = c^2
Now you take the square root of 74 and c^2
If you put the square root of 74 in a calculator you get about 8.6
So c = 8.6 or d = 8.6
