Answer:
Given - (a-b)²=7
(a²+b²) =29
To find - ab
Solution -
( a- b) ^2 = 7
(a^2 + b^2) = 29
Expanding the bracket by using identity
a^2 + b^2 -2ab = 7
29 - 2ab = 7 (given a^2 + b^2 = 29 )
-2ab = 7 -29
-2ab = (-22)
ab = (-22) /(-2)
ab = 11
To find the area of a circle you need to do pi times r(squared) So you should multiply pi times (4.9^2). So it should be 24.01*pi
The slope of the line is 17 because its in front of the varible
