James calculated the height of a cylinder that has a volume of 324
below.
cubic inches and a radius of 12 inches. his work is shown

v=bn
step 1: 3245 - 12h
step 2: 324 = 24 sh
324 24
step 3: 245 245
step 4: h-13.5
inches

what is the first error that james made when calculating the height of the cylinder?

in step 1, he substituted into the volume formula incorrectly.
in step 2, he calculated 122 incorrectly. it should be 144 rather than 24.
in step 4, the should have canceled, making the correct answer 13.5 cm.
james calculated the height of the cylinder correctly

In step 1, he substituted into the volume formula incorrectly.

Step-by-step explanation:

James calculated the height of a cylinder that has a volume of 324 cubic inches.

radius = 12 inches.

The formula for volume is =

So, James calculated wrongly by using the wrong formula.

The step 1 is wrong.

In step 1, he substituted into the volume formula incorrectly.

Step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
