Answer:
x = 3
Step-by-step explanation:
x + 9x + 5 = 35
=> x + 9x = 35 - 5
=> x + 9x = 30
=> 10x = 30
=> x = 30/10
=> x = 3
Answer:
3.225806%
Step-by-step explanation:
1.24*10^9/(1.28*10^9) = 1.24/1.28 = 1.03225806 which is a 3.225806% increase
Answer:
-2x^2 -2x + 4
Step-by-step explanation:
Distributive prop.
(-2x-4)(x-1)
-2x^2 + 2x - 4x + 4
-2x^2 -2x + 4
3(-1)-7= -10
3(0)-7= -7
3(1)-7= -4
3(2)-7= -1
3(3)-7= 2
therefore range = {-10,-7,-4,-1,2}
