Answer:
A) x = 2, x = 7
Step-by-step explanation:
x^2 + 14 = 9x
Subtract 9x from each side
x^2-9x + 14 = 9x-9x
x^2-9x + 14 = 0
What 2 numbers multiply to 14 and add to -9
-7*-2 = 14
-7+-2 = -9
(x-7)(x-2) = 0
Using the zero product property
x-7 = 0 x-2 =0
x=7 x=2
Answer:
20
Step-by-step explanation:
Substitute the given values:
A= 4
B= 3
C= 2
5(a+b)-3(b+c)
5(4+3)-3(3+2)
Add the numbers:
5(7)-3(5)
5•7 = 35 and 3•5= 15
35-15 =20
