So pretty much, 4g is 4 times g right? taking this into consideration, replace g with x1 and h with x4. Then you get 4 x 1 + 5 x 4. Since you're always supposed to multiply and then add (left to right), it would equal 4 + 20 which is 24. Good luck on your test.
Answer:
Step-by-step explanation:
The area will be increased by 4 times and volume will be increased by 8 times
Area of rectangular prism = 2 (lb+bh +hl)
When sides are doubled, Area = 2 (2l * 2b +2b *2h + 2h*2l)
= 4 * 2 (lb+bh +hl)
Volume of rectangular prism = lbh
When sides are doubled, Volume = 2l * 2h * 2b = 8 lbh
Answer:
D
Step-by-step explanation:
To inverse a function, switch the y for x and x for y and solve for y
f(x) = 2/(x-3)
y = 2/(x-3)
x = 2/(y-3)
x*(y-3) = 2
y-3 = 2/x
y = 2/x-3
y = 2/x - 3x/x
y = 2+3x/x
[D]

Cross multiplying, we get:

Thus the value of y for given proportion is 18.
