If the sol'ns are -9 and 9, then we can use this to form our eq'n:
(x - 9)(x + 9) = 0
x^2 - 81 = 0
so...
x^2 + z - 103 = x^2 -81
z - 103 = -81
z = -81 + 103
z = 22
Answer:
D. 
Step-by-step explanation:
given equation: 
Answer:
Volume is : l x w x h
=9 x 3 x 3.5
= 94.5 cm3
Rounded off the answer is 100
Step-by-step explanation:
Answer:
Solution:
{-5, 3}
Step-by-step explanation:
3x^2+6x=45
3x^2+6x - 45 = 0
(3x - 9)(x + 5) = 0
3x - 9 = 0; x = 3
x + 5 = 0
x = -5
Solution:
{-5, 3}
Not a lot of details, but the answer is:
