Simplifying

44 = 14 + -2a


Solving

44 = 14 + -2a


Solving for variable 'a'.


Move all terms containing a to the left, all other terms to the right.


Add '2a' to each side of the equation.

44 + 2a = 14 + -2a + 2a


Combine like terms: -2a + 2a = 0

44 + 2a = 14 + 0

44 + 2a = 14


Add '-44' to each side of the equation.

44 + -44 + 2a = 14 + -44


Combine like terms: 44 + -44 = 0

0 + 2a = 14 + -44

2a = 14 + -44


Combine like terms: 14 + -44 = -30

2a = -30


Divide each side by '2'.

a = -15


Simplifying

a = -15 p.s i hope i helped you ~ azu

To solve the equation 44 = 14 - 2a, we need to get a by itself, on one side of the equation. We can do this by first getting terms with a on one side and terms without it on the other side.

44 = 14 - 2a

To get a on one side, we need to eliminate 14 from the side with the -2a. We can do this by subtracting 14 from each side.

44 - 14 = 14 - 14 - 2a

-2a = 30

Now we want to get a single a, which can be accomplished by dividing both sides by -2.

-2/-2a 30/-2

a = -15

2) Calculate the surface<br> area of the cylinder:<br> 5 cm
AVprozaik [17]

Answer:

28π cm²

Step-by-step explanation:

The surface of a cylinder is given by the formula:

  • 2πrh + 2πr²

where r is the radius of the base, and h is the height.

Using the image, we can find that the radius of the cylinder would be 2 cm, and the height would be 5 cm.

Now, to find the surface area of the cylinder, we would have to plug in 2 for r (the radius of the base) and 5 for h (the height of the cylinder) into the formula for the surface area of a cylinder.

Now we plug in 2 for r and 5 for h for the equation for the surface area of a cylinder:

2π(2)(5) + 2π(2)² = 20π + 2π(4) = 20π + 8π = 28π

Remember, the radius and the height are given to us in cm, and w are solving for surface area, so the answer should be in cm² (square centimeters).

The surface area of the cylinder would be 28π cm².

28π cm² would be an exact answer. For the approximate answer, plug in 3.14 (most math classes use 3.14 to approximate π) for π.

I hope you find this helpful. :)

the length of AB_ is 9 cm a dilation with a scale factor of 2 is applied to AB_ what is the length of the image of AB after the
Minchanka [31]

The scale factor of two means you need to multiply the original length by 2:

9 x 2 = 18

The new length would be 18 cm.

PLEASE SOLVE AND CHECK. SHOW COMPLETE SOLUTION
Alex17521 [72]

<u>Solution</u><u>:</u>

\sqrt{4x + 13}  = x + 2

  • First square both sides.

=  > ( \sqrt{4x + 13} ) ^{2}  = (x + 2) ^{2}

  • Now, square root and square gets cancel out in the LHS. And in the RHS, apply the identity: (a + b)² = a² + 2ab + b².

=  > 4x + 13 =  {(x)}^{2}  + 2 \times x \times 2 + (2) ^{2} \\  =  > 4x + 13 =  {x}^{2}   + 4x + 4

  • Now, transpose 4x and 4 to LHS.

=  > 4x - 4x + 13 - 4 =  {x}^{2}  \\

  • Now, do the addition and subtraction.

=  >  {x}^{2}  = 9 \\  =  >  x =  \sqrt{9}  \\  =  > x = ±3

<u>Answer</u><u>:</u>

<u>x </u><u>=</u><u> </u><u>±</u><u> </u><u>3</u>

Hope you could understand.

If you have any query, feel free to ask.
