Elodia [21]

Answer:

2

Step-by-step explanation:

Given expression:

y^2 - 5y - 4

y = 6

Substitute y = 6 into the expression

y^2 - 5y - 4

6^2 - 5(6) - 4

(6*6) - (5*6) - 4

36 - 30 - 4

36 - 34

The side of a square is 11.2 cm. what is the length of the diagonal
Snowcat [4.5K]
You can work out the diagonal by using Pythagoras theorem. (a^2 = b^2 + c^2)

As it is a square, all 4 sides are the same so it would be:
11.2^2 + 11.2^2 = diagonal^2
250.88 = diagonal^2
Square root both sides to get what the diagonal is equal to.
diagonal is 15.8 cm
