A=bh
A/h bh/h
A/h=b
The answer s b= a/h
The area of triangle is equal to 1/2 multiplied by base and height. In this case, height is equal to b - 3 and area is equal to 19 b. thus the equation is
19 b = 0.5 (b-3 ) b b is then equal to 41 units. h is b - 3 equal to 38 units.
Answer:
<h3>note: all the twos are to the power</h3>
100=(x−1)2(y+3)
Step-by-step explanation:
Suppose the centre of the circle was at the origin (where the x axis crosses the y axis). Then the equation would be:
r2=x2+y2
The reason for this format is that the length of the radius (which is of fixed length) can be related to x and y by Pythagoras. However, the circle centre is not at the origin. It is at
(x,y)→(1,−3)
So we can mathematically make this work by 'theoretically' moving the actual centre to a new centre located at the origin.
Thus we would have:
r2=(x−1)2+(y−(−3))2
r2=(x−1)2+(y+3)2
But the radius is 10 so we have
(10)2=(x−1)2+(y+3)2
100=(x−1)2+(y+3

Step-by-step explanation:
I don't really know how to explain this
Answer:
107
Step-by-step explanation:
The formula for Area is Length x width. Take the first shape and multiply 7x5 which equals 35.
Then do the same thing for the second shape 8x9=72
Now add
35+72=107!! Hope this helped
