Answer:
x^2 +2x -5
Step-by-step explanation:
f(x) = 2x+3
g(x) = x^2 -8
f(x)+g(x) = 2x+3+ x^2 -8
Combine like terms
= x^2 +2x -5

Answer:
the answer is 589.4
Step-by-step explanation:
In doing this equation you do the order of operations:
(2.1 x 104)= 218.4
(3.5 x 106)= 371
you then add the answers together to get:
218.4 + 371 = 589.4
Answer:
Given : s||t
Exterior sides in opposite rays : ∠5 and ∠7 are supplementary
Definition of supplementary angles : m∠5 + m∠7 = 180°
If lines are ||, corresponding angles are equal : m∠1 = m∠5
Substitution : m∠1 + m∠7 = 180°
