Answer: 24
Step-by-step explanation:
Given :
b - 2a - c
a = - 7
b = 3
c = - 7
Substituting the values into the expression , we have
3 - 2 ( - 7 ) - ( - 7 )
⇒ 3 + 14 + 7
= 24
Answer:
18, 24, 8, 3
Step-by-step explanation:
8a = 42 - 18
8a = 24
a = 24 / 8
a = 3
To check, plug 3 into the equation
8(3) = 42-18
24 = 24
Answer:
28
Step-by-step explanation:
Answer:
y = 2(x+3)(x-3)
Step-by-step explanation:
y = a (x-x1) * (x-x2) * (x-x3) * ... (x-xn)
x 1 to n represents the roots
