Solving quadratic equations by factoring <br> m(m-3)=0
KatRina [158]
Because it has already been factored, we can solve it straight away. Now, since m is a variable, we yield the same result if m = 0 or m = 3 because we have two components to this equation.

We can either have m = 0 or m - 3 = 0
Hence, m is either 0 or 3

50 squared equals 2 + 25 squared equals 2 * 5 equals 10 what is wrong
Klio2033 [76]

Convert to an equation:

50^2=2+25^2=2*5=10

Simplify:

2500=625=10=10

What is wrong is that 2500 does not equal 625 which does not equal 10.

Estimate the perimeter of the figure to the nearest whole number.
ser-zykov [4K]

Answer:

See Explanation Below

Step-by-step explanation:

The question is incomplete (because the figure to calculate the perimeter is missing).

However from the comment attached to your question, I understand that the figure looks like a plus sign.

The perimeter of a plane shape is calculated by adding the length of each side of the shape.

Take for instance;

A square of length 5cm.

We know that a square has 4 equal sides; meaning that the length of the other sides are also 5cm

So, the perimeter of the square will be calculated as 5cm + 5cm + 5cm + 5cm = 20cm

Similarly, the perimeter of a triangle whose sides are 4ft, 3ft and 5ft will be calculated by adding up the length of the three sides.

Perimeter of the triangle = 4ft + 3ft + 5ft

Perimeter = 12ft.

Having explained how the perimeter of a plane shape is calculated; take for example, the attachment below.

(The sides are measured in centimetres)

The plus sign has 12 sides; Its perimeter is calculated by adding up the length of the 12 sides.

Perimeter = 3 + 7 + 7 + 5 + 5 + 5 + 5 + 2 + 2 + 4 + 4 + 3

Perimeter = 52cm
