Answer:
true
Step-by-step explanation:
sinA² + cosA²=1
⇔(1/2)² + cosA²=1
⇔cosA=±(√3/2)
Answer:
Always
Step-by-step explanation:
Similar figures are always the same shape, but not always the same size. If they have they same size, then they are also congruent.
Answer:
5 months
Step-by-step explanation:

162.50=27.50x+25
162.50-25=27.50x+25-25
137.50=27.50x
137.50/27.50=x
5=x
hope this helps :)
Answer:
(f + g)(x) = x² + 4x - 4
Step-by-step explanation:
The statement (f + g)(x) is the same as f(x) + g(x). In other words, the question simply wants you to add the two functions together.
f(x) = 4x + 1
g(x) = x² - 5
(f + g)(x) <----- Original statement
f(x) + g(x) <----- Rewrite
(4x + 1) + (x² - 5) <----- Substitute the equations in f(x) and g(x)
4x + x² - 4 <----- Add 1 and -5
x² + 4x - 4 <----- Rearrange the terms
