(s o t)(x)=s(t(x))
(s o t)(-7)=s(t(-7))
x=-7→t(-7)=3(-7)→t(-7)=-21
(s o t)(-7)=s(t(-7))=s(-21)
x=-21→s(-21)=2-(-21)^2=2-441→s(-21)=-439
(s o t)(-7)=s(t(-7))=s(-21)=-439
Answer: Option A -439
Exponents if those are the answer it bc the second number is an exponent
3^3= 27
4^3=64
3^4=81
Recognize that the triangle is isosceles, so the two side lengths are equal.
b = 2√2
Recognize it is a right triangle, so you can use the Pythagorean theorem to compute the length of "a".
a^2 = (2√2)^2 +(2√2)^2
a^2 = 8 +8 = 16
a = √16
a = 4
