Answer:
-60
Step-by-step explanation:
first you have to input 4 to the equation g(x).
2(4) + 2(4) = 16
now input it to f(x)
-4(16) + 4 = -60
i feel like this is correct
Answer:
A
Step-by-step explanation:
To find the volume of a rectangular box, multiply all its dimensions together.

So B is 6x bigger than figure A and A is only half the size of B
Answer:
A). 15
B). -1.2
Step-by-step explanation:
A). [10(x+3)]-20 = 160
10x+30-20 = 160
10x+10 = 160
10x = 160-10
10x = 150
x = 150/10
x = 15
B). 5{[4(8+(5x))]-9} = 85
5(32+20x+9) = 85
5(32+9+20x) = 85
5(41+20x) = 85
205+100x = 85
100x = 85-205
100x = -120
100x/100 = -120/100
x = -1.2
