Fiona wrote out the description of each step for her multiplication of the binomial and trinomial (2x – 3)(5x2 – 2x + 7).
Valentin [98]

Answer:

Step 2

Step-by-step explanation:

Fiona did mistake step 2.

Use the distributive property to multiply -3 times each term in the trinomial.

The correct result is

-3(5x^2 - 2x + 7) = -15x^2 + 6x - 21

Fiona written -6x instead of + 6x.

That's the error.

The answer is "Step 2"

Hope you will understand the concept.

Thank you.

Perimeter of a triangle is 27cm,if two sides measure 9cm and 7.8cm,find the measure of third side?
fredd [130]

Answer:

10.2cm

Step-by-step explanation:

Perimeter is the sum of the lengths of all sides.

1st side: 9cm

2nd side: 7.8cm

Perimeter: 27cm

Perimeter = 1st + 2nd +3rd side of a triangle

27cm = 9cm +7.8cm + 3rd side

3rd side = 27cm - 9cm -7.8cm

              = 10.2cm
