Answer:
geometric
Step-by-step explanation:
The differences are not constant, so the sequence cannot be arithmetic. The common ratio is -2, so the sequence is geometric.
Answer:
30
Step-by-step explanation:
<A=90°(opposite Angles)
➜2x+x+90=180
➜3x+90=180
➜3x=180-90
➜3x=90
➜x=90/3
<h3>➜x=30</h3>
Answer:
<h2><u><em>
24 triangles</em></u></h2>
Step-by-step explanation:
in the picture
So the domain<span> is "all </span>x<span>". To </span>find<span> the </span>domain, I'll ignore the "x<span> + 2" in the numerator (since the numerator does </span>not<span> cause division by zero) and instead I'll look at the denominator. I'll set the denominator equal to zero, and solve. The </span>x-values<span> in the solution will be the </span>x-values<span> which would cause division by zero.</span>
Answer:
(f+g)(x) = x^2 +10x +7
Step-by-step explanation:
(f+g)(x) = f(x) +g(x) = (15x +7) +(x^2 -5x)
= x^2 +x(15 -5) +7
= x^2 +10x +7
