You haven't provided the expressions to choose from.
4⁻² × 7⁻² = (4×7)⁻² = 28⁻² = 1/28²
It should be 9 m :)
4x - 3y = 4
-3x + 3y = -6
x = -2
-2 - y = 2
-y = 4
y = -4
(-2,-4)
A is the correct answer.
First do 6 times 6 and then do 36 times 3.14 to get 113.04.
Then do 4 times 4 to get 16 times 3.14 for 50.24
Last do 113 minus 50 for 63 squared.
