That’s the answer and also the steps to getting that answer
Answer:
-9
Step-by-step explanation:
-3 times -3 = -9.
Step-by-step explanation:
A) 45
B) 6
C) 6.7082039326
Let the shorter leg = a.
The longer leg, b = a + 4.
The hypotenuse, c = a + 8
a^2 + b^2 = c^2
a^2 + (a + 4)^2 = (a + 8)^2
a^2 + a^2 + 8a + 16 = a^2 + 16a + 64
a^2 - 8a - 48 = 0
(a - 12)(a + 4) = 0
a - 12 = 0 or a + 4 = 0
a = 12 or a = -4
a = -4 is discarded because it is negative.
a = 12
b = 16
c = 20
The lengths are 12 m, 16 m, and 20 m.
For the first one;
2≥x<13
And the second one;
65≥x
