Answer:
-7
Step-by-step explanation:
f(3) = 2(3)+3 = 9
g(4) = 2^4 = 16
9 - 16 = -7
Answer:
x = 1± 3i
Step-by-step explanation:
x^2-2x+10=0
We can complete the square to solve by subtracting 10 from each side
x^2-2x+10-10=-10
x^2 -2x = -10
We need to add (2/2) ^2 to each side or 1
x^2 -2x+1 = -10 +1
x^2 -2x+1 = -9
The left side factors into (x- (2/2) ) ^2
(x-1) ^2 = -9
Take the square root of each side
sqrt((x-1) ^2 =± sqrt(-9)
x-1 = ±sqrt(-1) sqrt(3)
Remember the sqrt(-1) = i
x-1 = ± 3i
Add 1 to each side
x-1+1 = 1± 3i
x = 1± 3i

Step-by-step explanation:
![1120 = 20x + 300](https://tex.z-dn.net/?f=1120%20%3D%2020x%20%2B%20300)
![1120 - 300 = 20x](https://tex.z-dn.net/?f=1120%20-%20300%20%3D%2020x)
![820 = 20x](https://tex.z-dn.net/?f=820%20%3D%2020x)
![x = 41](https://tex.z-dn.net/?f=x%20%3D%2041)
Her goal is 60 boxes. this is all the work i did basically i set it up as an equation of looking for x and that’s my work so i hope it helps :)
Answer:
-8b - 32
Step-by-step explanation:
Distribute the 8 to each term in the parentheses:
8(-b) = -8b
8(-4) = -32
Add these two terms together:
-8b - 32 is the simplified expression
