Answer:
False
Step-by-step explanation:
The same function input (the first number in the pair) cannot have two different outputs (the second number in the pair).
(6, 4) 4 is one output.
(6, -4) -4 is another output.
Since all sides of the square are equal, therefore area of square can be calculated using the following rule:
area of square = side^2
200 = (side length)^2
therefore,
the length of each side is sqrt(200) = 14.14 ft

If you can use your phone in class, I highly suggest the desmos app because you can just put the equations in and it shows you everything
Answer:
see explanation
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
= 
( cross- multiply )
9x = 72 ⇒ x = 8
Also
= ( cross- multiply )
6a = 45 ⇒ a = 7.5
And
= ( cross- multiply )
6b = 63 ⇒ b = 10.5
Corresponding angles in the 2 figures are congruent, thus
∠s = 83°
Each lower base angle is supplementary to the upper base angle on the same side, hence
∠r = 180° - 30° = 150°
