A1 + a1r + a1r2 + a1r3 + a1r4 and so on
Always will be your answer ;D
Let the first number be x
let the second number be y
therefore, x+y=12........1
and x×y=-64................2
factors of 64 include
1 and 64,
2 and 32,
4 and 16
here we find out that 16+-4=12 and that 16×-4=-64
∴, x=16
and y=-4
please mark as brainliest
The square root of 147 when rounded to the nearest tenth is about 12.1
