Answer:
±6
Step-by-step explanation:
Given the mathematical expression;
√36 < √42 < √49
But, √36 = 6 * 6 = 6²
√49 = 7 * 7 = 7²
Simplifying further, we would substitute the new values respectively;
±[6] < √42 < ±[7]
Therefore, evaluating √36 is equal to ±6.

For this case we have that the area is given by:
A = (w) * (l)
Where,
w: width
l: long
Substituting we have:
66 = (w) * (w + 5)
Rewriting
w ^ 2 + 5w - 66 = 0
(w + 11) * (w-6) = 0
Using the positive root we have:
w = 6
Answer:
the width of the frame is:
w = 6 cm
Answer:
The answer is that y = 3
Step-by-step explanation:
In order to find y, you must first find x. You can do that by noting the two angles next to each other create a straight line and therefore are equal to 180 degrees.
(4x + 23) + (9x - 38) = 180
13x - 15 = 180
13x = 195
x = 15
Now that we have the value of x, we can use the alternating interior angle theorem to tell that 27y - 1 is equal to 4x + 23. Using our value for x, we can solve for y.
27y - 1 = 4x + 23
27y - 1 = 4(15) + 23
27y - 1 = 60 + 23
27y - 1 = 83
27y = 84
y = 3
No because 5^2 +10^2 is not equavalent to 13^2
by using the pythagoras' theorem
