Answer:
The hypotenuse is the longest side in a triangle.
a^2=b^2+c^2.
14^2=9^2+c^2.
c^2=196-81.
c^2=115.
c=√115.
c=10.72~11cm

Answer:
the equation is equivalent, y is any number
Step-by-step explanation:
-3(3y-7) = 21-9y
-9y + 21 = 21 - 9y
-9y = -9y
y=y
any number will satisfy y=y
Answer:
X = 10 and X = -4
Step-by-step explanation:
(x-3)^2-38=11
(x-3)^2 = 11 +38
(x-3) ^2 = 49
Taking square root on both sides
√(x-3) ^2 = √ 49
X-3 = +7, -7
X = 7 +3, X= -7+3
X = 10 X = -4
So, it has got two solutions
