What is the answer to this : Expand y(y + 10)

Mathematics
1 answer:
Ivenika [448]3 years ago

When expanding brackets, you have to multiply whatever is outside by everything on the inside
The calculations you would do are
y x y
y x 10

Whenever a value is multiplied by itself once, we describe it as the value squared (²)
y x y can be written as y²

y x 10 is the same as 10 lots of y
In algebra, we don't write multiplication signs as it can get confusing so we write the number directly in front of the letter    10y

When put together, y(y + 10) expanded is

y² + 10y

Urgent!! Can anyone help me with this step-by-step
ehidna [41]

Answer:

x = 28

Step-by-step explanation:

It gives you the value of the midsegment, which is 16. So you need to set up the equation as:

x + 4 = 2 × 16

You're multiplying 16 (the midsegment) by 2, because the it is <em>half</em> of x + 4, and you need to be able to set both parts of the equation equal to each other.

x + 4 = 32

Then, subtract 4 from both sides:

x + 4 = 32

   -4     -4

_________

This gives you the answer of:

x = 28
