$6x$5=$30
$50-$30=$20
So 5 books?
Or
50=6x5+x
x=20
2^2 - 5t + 12 = 0
4 - 5t + 12 = 0
-5t + 16 = 0
-5t = -16
t = 16/5
Answer: 16/5 in fraction form or 3.2 in decimal form
No, it is not. If you plug 4 into the equation in the place of x, you get 13=2(4)+4
13=8+4
13=12
It equals 12, not 13.
Answer:
292 inches^2
Step-by-step explanation:
So to start off this is a picture of the fish tank.
Next we will find the area of the bottom and top rectangles.
The side lenghts for those two is 7 and 8.
So the area of one is 56 and the area of 2 is 112 inches^2.
Now we will find the area of the left and right rectangles.
The side lenghts are 6 and 8.
So the area of 2 is 96 inches^2.
Now for the front and back rectangles.
The side lenghts for those two are 6 and 7.
So the area of both is 84 inches^2.
So after adding all the areas up the surface area is 292 inches^2.
