(4)(1) * (4(2)-2(1))
4 * (8-2)
4*6
24
Answer:
b = 60
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 63² = 87²
b² + 3969 = 7569 ( subtract 3969 from both sides )
b² = 3600 ( take the square root of both sides )
b = 
= 60
Y-2=-3/5x -6/5
(5)(y-2)=(-3/5x-6/5)(5)
5y-10=-3x-6
5y+2x=4
Answer:
D. All the choices are correct
I think that's the right answer, if it isn't than my bad!!
Answer: 24cm²
Step-by-step explanation:
Let square with length 5cm be represented with A, and square with 7cm be represented with B.
Area of a square is L²
Square A will have an area of 5² = 25cm²
Square B will have an area of 7² = 49cm²
Total area between the two squares will be = Area of Square (B - A)
i.e.
Total Area = 49cm² - 25cm² = 24cm²
