Answer: 52 square cm
Step-by-step explanation:
The given surface area formula of a rectangular prism,
S = 2 wl + 2 lh + 2 hw
Where is the length, w is the width and h is the height of the prism,
Here, length, l = 2 cm,
Width, w = 3 cm
And, Height, h = 4 cm
Thus,The required surface area of the prism,
S = 2 × 3 × 2 + 2 × 2 × 4 + 2 × 4 × 3
S = 12 + 16 + 24 = 52 square cm.
8x + 4 = 5x - 11
Subtract 5x from both sides:
3x + 4 = -11
Subtract 4 from both sides:
3x = -15
Divide both sides by 3:
x = -5
Answer : x = -5
Answer:
D. H = 2.1t + 12
Step-by-step explanation:
Let us assume the t be the time in minutes
And h be the water level
Now before reaching to the equation that need to be used
before this, determine the inches per minute i.e.
= 54 inches - 12 inches
= 42 inches in 20 minutes.
Now for per minute, it would be
= 42 inches ÷ 20 minutes
= 2.1 inches per minute
After this, multiply the inches per minute with the minutes t and add the sale to the beginning value i.e. 12
So the equation is
H = 2.1t + 12
hence, the last option is correct
