Answer:

See attached table

Step-by-step explanation:

Given base b,

the required formulas are:

Area of base = b^2

height: solve for h in 2b^2+4*bh = S =54

where S is the surface of 54

Substitute and solve for h,

h =  (S - 2b^2)/(4b) = (54-2b^2)/(4b) = (27-b^2)/(2b)

The volume is equal to base area times height, or

V = b^2(h)

The completed table is attached.

Answer:

9

Step-by-step explanation:

Area of a triangle=(base*height)/2

1) Input the values

54=(12h)/2

2) Multiply both sides by 2

54*2=(12h/2)2

108=12h

3) Divide both sides by 12

108/12=12h/12

9=h

I hope this helps! Please comment if you have any questions.

Answer:

The answer is

y = 6x + 43

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

The original line is y = 6x + 1

Comparing with the general equation above

Slope = 6

Since the lines are parallel their slope are also the same

Slope of parallel line = 6

The equation of the line using point (-7,1) and slope 6 is

We have the final answer as

y = 6x + 43

Step-by-step explanation:

srry if this is wring, its what i got also pls give brainliest, im trying to get to vituoso :3
