The first statement comes about because
a could be (say) 5
b could be (say) 6
Then c would be square root of 25 + 36 = 61 which is irrational.
I'm not sure of the wording of the second one. It reads like (5 + 6)^2 = 121 the two rationals added together make a rational number in my example. So I think that part is wrong. the second part is correct. For example sqrt(5) + sqrt(6) doesn't produce anything that is rational.
It doesn't have to. pi^2 + [cube root(10)]^2 does not produce anything rational and that is certainly not a perfect square. My first example shows that as well
I think the last one might be true.
Linear you are going up a hill at a 30 degrees angle at a constant speed of 40 miles per hour
Nonlinear when ever you bake cookies you cant touch them right away or you burn your hand but they decrease in temperature fast then level out

Inequality can be used to find the domain of f(x) is x ≥ -
f(x) =
for real f(x)
4x + 9 ≥ 0
⇒ x ≥ -
Thus, Inequality can be used to find the domain of f(x) = is x ≥ -

Answer:
4 and (q − 18 + p)
Step-by-step explanation:
Given:
4(q−18+p)
The factors are
4 and (q − 18 + p)
A factor refers to something which is multiplied by something else. It could be a number, variable, term, or a longer expression.
For example. The factors of the expression 6x(y +2)
are 6, x and (y+2)
