Answer: A (w=2a+3)
Step-by-step explanation: The answer is A because for every week after the tiger is born it gains 2 pounds. that's the w=2a part. The +3 is there because the tiger started with 3 pounds.
10 in; if the original 100% was 5 in, then you multiply that by 2.
Short Answer: x = 2*sqrt(2)
The Pythagorean Theorem states that
a^2 + b^2 = c^2
Givens
a = 2
b = 2
c = ???
Sub and solve
2^2 + 2^2 = c^2
c^2 = 4 + 4
c^2 = 8 Take the sqrt of both sides of the equation
sqrt(c^2) = sqrt(8) Express 8 in it's prime factor form.
sqrt(c^2) = sqrt(2 * 2 * 2)
The rule about square roots is
If you have a pair of prime factors under the root sign, you take out one of the prime factors and throw the other one away.
sqrt(c^2) = 2*sqr(2)
Answer x = 2*sqrt(2)
