Perimeter is the distance around the outside.
A square has 4 equal sides:
Perimeter = 21 x 4 = 84 yards
Let y=x+6 be equation 1...
Replace equation 1 in equation 2
X+6 =-2x-3
X+2x = -3 -6
3x = -9
X = -3
Answer:
11: A 12: B
Step-by-step explanation:
-29 <-21 and a coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression
Answer:
see explanation
Step-by-step explanation:
Using the identities
tanx = , cotx =
Consider the left side
=
=
=
= × ← cancel cosx on numerator/ denominator
= sin²x
= right side
A squared +b squared =c squared
so 24x24=576
18x18=324
576+324=900
square root of 900=30
the diagonol is 30
