Answer:
x = -9 ; x = 7
Step-by-step explanation:
We have to find two numbers whose product is -63 and whose sum is 2
the two numbers are 9 and -7
(x+9)(x-7) = 0
x = -9
x = 7
u must use the formula
so, the answer is 10 units²
It’s 9inches ! Because area=width •length
Therefor you can divide 63 by 7 to get 9
The scientific notation for this is :-6x10⁷
